Meaning vectors
A meaning vector is what lets a search for "cheap flights" find a page about "low-cost airfare". Opensolr makes one for every crawled and pushed document on its own; these calls give the same vectors to your own code, made by the same model, so they match the ones in your index.
Every call here goes to https://api.opensolr.com. Each text turned into a vector counts against the monthly AI allowance of the account that owns the index; a vector already in cache costs nothing (API Quota).
The calls
embedOne text, or one search question, turned into a meaning vector.
Referencebatch_embedMany texts turned into vectors in one call; each text counts as one request.
Referenceembed_opensolr_indexAdd meaning vectors to the documents already in an index.
Referenceenrich_textThe language, locale, sentiment and, when you ask, the vector of a list of texts, worked out exactly as for a pushed document.
