Thoughts on Algolia vs. Solr and Elasticsearch

True though this assumes these direct words are mentioned in the text (assuming know synonyms). Algolia has basic synonym functionality but ES gives you a lot more power here.

Further the more words you remove, the less constrained the results get possibly creating a lot of noise. Though I assume you remove based on document frequency, which helps.

This would be a problem with this strategy regardless of search engine (ES or Algolia)

Algolia has actually a very decent synonyms support:

  * mono & multi-words synonyms,

  * typo-tolerance is compliant with synonyms,

  * matching synonyms are highlighted,

  * prefix search works also on synonyms (even on multi words).

A v2 of the synonyms API will be released in the next few days including:

  * dedicated API endpoints (leveraging existing synonyms but also Algolia's "alternative corrections" and "placeholders")

  * new edition UI (with search & filtering capabilities)

  * one/bi direction synonyms

nice I stand corrected. The first list is what I knew about!

This is actually an interesting dividing line. As you get more sophisticated modeling fuzzier concepts over just synonyms (synonyms are just one tool for this) then I think you get out of algolias sweet spot. When text pushed into a feature space (which happens quite a lot when you're mapping vernaculars) you begin to gain more from Solr and ESs depth of customizability.
