Metadata indexes are similar to main term indexes, but store lesser data compared to main term index data. Typically, all the main term indexes settings work well for metadata indexes settings. The default setting is:
<SystemProperty name="omniq.index.metadata.numSegments" value="2"/>
If you are indexing more than 250,000 documents in a document store, increase the number of metadata index segments to, for example, 4 or 5.
