Opensolr Search for Drupal 3.5.0 Adds the Lexical Only Search Mode
Opensolr Search for Drupal 3.5.0 adds the Lexical Only search mode, matching the option already present in the Opensolr admin.
01 What Lexical Only does
Selecting Lexical Only skips the embedding request entirely and runs pure lexical search. Nothing is sent for vectorisation, and the query is answered on term matching alone.
02 Minimum Relevance Score is auto-zeroed
A relevance threshold calibrated for hybrid scoring would filter out perfectly good lexical results. So when Lexical Only is selected, the Minimum Relevance Score is automatically set to zero, both on save and again at query time.
The same feature is available across the stack: Opensolr admin, Drupal module and WordPress plugin.
