Hi Dilip,
I'm afraid I can't help you out, but maybe my 2 cents might help you in the right direction.
Are you searching through the Query Tester or through API?
You might already noticed this, but to me it seems:
1. Only results that **start** with light (or after space, so that word also 'starts' with light) are returned. If you use APIcall then maybe look at the type of search to check whether a complete match or also partial match will be returned.
2. Query Tester I don't know, but in API you can specify fuzziness. If you don't set it, it will be on auto. That means based on the lenght of the search term 1 or more characters will be searched fuzzy. Also see documentation link below.
Default for a 5 character search, like 'light', is 1 fuzzy edit. Since lightsun, sunlighting ,sunlight are more than 6 characters they will not be found with this fuzzy setting. Aditionally sunlighting and sunlight will also not be found because of issue 1 probably. Light and (sun) light are within 1 fuzzy edit of 'ligt' however, and are therefore returned.
[Common options | Elasticsearch Guide [7.15] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/common-options.html#fuzziness)
Good luck!

Hey [DILIP\_SHARMA](https://discuss.elastic.co/u/DILIP_SHARMA),
App Search will match on prefixes and fuzziness. It won't find _contains_ type matches. It looks at each "term" in individually to determine matches.
sun light - Match - Exact match on the second term.
sunlighting - No match - No prefix match, and not similar enough for fuzziness.
lightsun - Match - Prefix match.
light - Match - Exact match.
sunlight - No match - No prefix match, and not similar enough for fuzziness.
sun - Not a match.
You could try adjusting the "Precision tuning" slider on the Relevance Tuning screen. But unfortunately, I think even if you have it entirely tuned for Recall we still won't match on _contains_.

You might need to resort to creating [Synonyms Guide | Elastic App Search Documentation [7.15] | Elastic](https://www.elastic.co/guide/en/app-search/current/synonyms-guide.html) for cases like this.
