A question on the workings of the weights we set. We sometimes experience that when changing the weighting settings (adjusting given weights up or down), some searches go from X results to 0 results. This seems counterintuitive. If a search yields results with some weight settings, it should always return some results with other settings. Only parameters set are the

query_by

,

query_by_weights

and

text_match_type

(

max_weight

). If I change weights from "50,30,10,59,20,30,20,1,60,1,1" to "*60*,30,10,59,20,30,20,1,60,1,1" I go from zero to 127 hits What can cause a given search to yield zero results just by adjusting the weights?

Hey Jesper, This aligns with how Typesense handles searches to improve performance. You can read a bit more here: https://typesense.org/docs/guide/faqs.html#when-i-search-for-a-short-string-i-don-t-get-all-results-how-do-i-address-this Could you try increasing your max_candidates parameter or even try using exhaustive_search?

Doesn't make a difference. Just seems like synonyms only match the highest weight property and disregard the rest

Is this behaviour only when using synonym?

Yes. I get two different results when searching for the "root" and when I search for the synonym

No, doesn't seem intended. CC: @Kishore Nallan

I checked on the logic used. All we do is this: 1. Take the query tokens 2. Try to match it against all the synonym rules for substitution. We try from the largest to smallest substitution possible (i.e. phrases preferred over individual words) 3. Query it Can you please post an exact query where this happens?

I have difficulties reproducing in a simple index with few docs and simple data. I can reproduce easily with a simple query in a prod index. I'll send you a PM
