[#41049] Error during term expansion. [#90056] The expansion of [ ] yielded too many results (max [100,000]) Clearwell eDiscovery Platform

Problem

Performing a search in Veritas Clearwell eDiscovery displays an error in the results pane.

Error Message

[#41049] Error during term expansion. [#90056] The expansion of [ <part of search query>] yielded too many results (max [100,000])

Cause

In the query string is a wildcard that creates over the set limit of terms when expanded across the document base being searched against.

Solution

Option #1. Alter the search query to decrease the number of terms produced from the wildcard(s).

Option #2. Change the system property (esa.textengine.expander.maxresults) to temporarily increase the limit.

Note: It is essential that if the property change is made, it must be changed back post-search to ensure that other searches do not inadvertently consume excess processing power.

2. Click System
3. Click Support Features
