Search configuration options

Use these settings to optimize the search features in Insight Surveillance.

Allow search and capture of existing items	Specifies whether, when you set the criteria for a new search, you can choose to include previously-captured items in the search results. By default, you have the option to do so.
Buffer Since Last Run	When you select a schedule to use when you define the criteria for a new search, you can select Since last run in the Date range section. This option instructs Insight Surveillance to search new items that have arrived since you last ran this scheduled search. In the Start box, you enter the date to be taken as a starting point for the first run of the search. By default, Since last run searches from the date of the last run (or the Start date for the first search) to the current day minus 1 (that is, up to yesterday). If required, you can change this interval to search to the current day minus n days. To use Since last run with any searches that run more than once a day, set the interval to 0.
Combine subject and content fields with OR	When you search for words in both the subject of an item and its content, specifies whether to find only those items that meet one or both criteria. By default, Insight Surveillance finds only those items that meet both criteria.
Disable Search against Other Departments	Specifies whether, when you define the criteria for a new search, the Other Depts option in the Author & Recipients area is available. By default, Insight Surveillance does let you conduct searches against other departments.
Disable search results preview	If set to true, prevents users who conduct a search in a research folder from previewing the search results. By default, Insight Surveillance does not stop users from previewing these items.
Enable automatic synchronization of index volumes	Specifies whether Insight Surveillance should automatically synchronize the index volumes for an archive when it encounters any unknown index volumes during a search. By default, Insight Surveillance synchronizes the index volumes automatically.
Enable Search Threads	Specifies whether to enable or disable all search facilities. By default, Insight Surveillance enables these facilities.
Error search if index is rebuilding or failed	Specifies whether the search of a particular archive returns an error if its index is offline, rebuilding, or failed. By default, Insight Surveillance returns an error in these circumstances.
Error search if missing items or content	Specifies whether the search of a particular archive returns an error if its index has failed to index either an indexable archived item or the content of the item. The default setting is false (not enabled).
Error search if index requires width normalization	Specifies whether the search of a particular archive returns an error if its index must be rebuilt to handle full-width characters correctly. The default setting is Off.
Fail search of archive if archive has been copied or moved	Specifies whether to mark as failed a search of a moved or copied archive, if the destination archive is not included in the search. The default is False, which means that Insight Surveillance produces a warning when searching such archives, but it does not mark them as failed.
Guaranteed Sample search timeout (mins)	Specifies the number of minutes for which guaranteed sample searches run before Insight Surveillance automatically accepts them and uses the results for sampling. The default is 240 minutes.
Hotword Set Tag	Specifies the tag with which Insight Surveillance prefixes hotword sets when you enter them in the criteria for a new search. The default is HWS.
Hotword Tag	Specifies the tag with which Insight Surveillance prefixes hotwords when you enter them in the criteria for a new search. The default is HW.
Maximum number of searches listed in filters	For areas of Insight Surveillance that list searches from which you can choose, specifies the maximum number of searches to include in the list. The default is 250.
Maximum Search Retries	Specifies the number of times that Insight Surveillance tries to search an archive before giving up. Enter a value in the range 1 through 50, where the default is 5.
Number of acceptance search Threads	Specifies the number of threads that are assigned to accepting search result sets. For example, the default setting of 5 means that no more than five search results sets are accepted at a time. Enter a value in the range 1 through 10.
Number of delete search Threads	Specifies the number of threads that are assigned to deleting search result sets. For example, the default setting of 2 means that no more than two search results sets are deleted at a time. Enter a value in the range 1 through 10.
Number of sampling search Threads	Specifies the number of threads that are assigned to sampling search result sets. For example, the default setting of 5 means that no more than five search results sets are sampled at a time. Enter a value in the range 1 through 10.
Number of Vault search Threads	Specifies the number of threads that are assigned to searching archives per index server. For example, the default setting of 10 means that no more than 10 archives are searched per Enterprise Vault server at a time. Enter a value in the range 1 through 10.
Only allow 'Research this message' on the first selected message	Specifies whether, when you click multiple items in the Review pane and then click Search, Insight Surveillance lets you specify the search criteria for each of the selected items or only for the first of the selected items.
Optimize search based on oldest and youngest items	When set to True, improves performance by excluding from a search those archives that Insight Surveillance has determined do not contain any items in the date range that you have specified in your search criteria. The default setting is False, which means that Insight Surveillance searches all the available archives, regardless of whether their contents fall within your specified date range or not. Use this setting with "Synchronize thread checking period (sec)", which is one of the Vault Directory Synchronization configuration options. If you set "Optimize search based on oldest and youngest items" to True, you must lower the setting for "Synchronize thread checking period (sec)" to ensure that Insight Surveillance does not run searches against out-of-date data. For example, you can lower the setting to 3600 seconds (one hour).
Perform Guaranteed Sample searches against sampling-eligible archives only	Specifies whether to limit guaranteed sample searches to the types of archives that are eligible for random sampling: Exchange Journal, Domino Journal, SMTP, and Shared. By default, Insight Surveillance limits guaranteed sample searches to these archive types to improve search performance. However, you may want to include other types of archives in guaranteed sample searches if, for example, Enterprise Vault is archiving SMTP items to them. This setting replaces the setting that was called "Ignore non journal archives for Guaranteed Sample searches" in earlier versions of Insight Surveillance.
Require 'Author' / 'Content' / 'From Date' / 'Recipients' / 'Subject' / 'To Date' to be specified	Specifies whether it is mandatory to enter the designated criteria before you can perform a search. By default, these criteria are optional. You may want to make them mandatory to prevent searches from returning an overwhelming number of results.
Retry time when index service is busy (min)	Specifies the frequency in minutes with which Insight Surveillance tries to access an Enterprise Vault Indexing service that is too busy to perform a search. Enter a value in the range 1 through 300, where the default is 5.
Retry time when index service not running (min)	Specifies the frequency in minutes with which Insight Surveillance tries to access an Enterprise Vault Indexing service that is unavailable. Enter a value in the range 1 through 300, where the default is 5.
Return only top messages in search results	Specifies whether searches return the top-level items only. Setting this option to Off means that all files attached to the top-level items are displayed in search results.
Save SMTP subject rather than filename	For items that were archived using File System Archiving (FSA), specifies whether to show the SMTP message subject rather than the FSA file name in the Review pane.
Search result page refresh time	Specifies the frequency in seconds with which Insight Surveillance refreshes the results summary page during a running search. Enter a value in the range 1 through 300, where the default is 10.
Search timeout (hours)	Specifies the maximum time in hours that Insight Surveillance allows for searches to complete. The default is four hours.
Searches page refresh time	Specifies the frequency in seconds with which Insight Surveillance refreshes the Searches pane for a department. Enter a value in the range 1 through 300, where the default is 20.
Show Application Search Tree 'Constrain Tree Height' option	When you define the criteria for a new search, specifies whether a Constrain tree height option is available in the Authors & Recipients area. When selected, this option fixes the height of the department tree view in the Authors & Recipients area. By default, Insight Surveillance hides the option.
Show Application Search Tree 'Expand All' option	When you define the criteria for a new search, specifies whether an Expand All link is available in the Authors & Recipients area. Clicking this link expands all the departments in the tree view. By default, Insight Surveillance hides the link.
Show 'Guaranteed Sample' option for new searches	Specifies whether you can create Guaranteed Sample searches. By default, you can.
Show Search Result In Progress	Specifies whether users can access the Review pane while a search is in progress, so that they can immediately start to review the items that Insight Surveillance has found. By default, Insight Surveillance permits this.
Total number of search results worker threads	Specifies the maximum number of search results worker threads that are allowed to run on the system. These threads handle the processing of search results returned from the archive. The maximum value is 5, and the default is 2.
Total number of search threads	Specifies the maximum number of search threads that are allowed to run on the system across all index volumes. The maximum value is 500, and the default is 100.
Use sequence number for searches	Optimizes performance for searches that return more than 50,000 results. By default, this option is enabled.
When service starts, wait before synchronizing Index Services (minutes)	Specifies the number of minutes that Insight Surveillance waits at startup before synchronizing with available index services. Enter a value in the range 0 through 300, where the default is 0.
When service starts, wait before starting Vault Searches (minutes)	Specifies the number of minutes that Insight Surveillance waits at startup before searching the archives for items. Enter a value in the range 0 through 300, where the default is 0.
