Opensolr Search for WordPress 1.0.7 Adds the Lexical Only Search Mode
Opensolr Search for WordPress 1.0.7 adds the Lexical Only search mode, bringing the plugin in line with the Opensolr admin and the Drupal module.
01 An explicit opt-out from vector search
Lexical Only is a deliberate opt-out rather than a fallback. When it is selected, no embedding API call is made at all, and the search runs through the lexical edismax path.
No way to state, in the plugin, that a site should never call the embedding API.
Lexical Only: no embedding call, queries run through the lexical edismax path.
02 The Minimum Relevance Score follows the mode
Picking the Lexical Only radio auto-zeroes the Minimum Relevance Score slider straight away. The backend enforces the same thing on save and again at query time, so the setting cannot drift out of step with the mode. A yellow note in the Search Mode section explains the coupling.
