10/29/2021, 1:02 PM@Kishore Nallan I saw the issue regarding exhaustive highlighting and wanted to ask if there was any update regarding multiple matches snippeting: https://typesense-community.slack.com/archives/C01P749MET0/p1629833031204400?thread_ts=1629830554.200800&cid=C01P749MET0

10/29/2021, 1:07 PMHave you tried 0.22.0.rcs21 build?
Kishore Nallan
10/29/2021, 1:07 PMOh wait this is about highlighting all instances of a match within a document.

10/29/2021, 1:09 PMWe made a bunch of highlight improvements in 0.22.. I have to verify if multiple highlights are now possible for the full field.

10/29/2021, 1:31 PM@bnfd I just checked. If you list the fields in
highlight_full_fieldsKishore Nallan
10/29/2021, 1:32 PMPlease try it out on
0.22.0.rcs21b
bnfd
10/29/2021, 1:33 PMAh this is without snippeting, right?

Kishore Nallan
10/29/2021, 1:33 PMYes, snippet is meant for highlighting the best matched portion.
Kishore Nallan
10/29/2021, 1:33 PMYou want multiple snippets from various parts of the document?

10/29/2021, 1:34 PMYes

Kishore Nallan
10/29/2021, 1:34 PMThat is not possible because Typesense scores documents on the best matched portion.
Kishore Nallan
10/29/2021, 1:34 PMI mean, if we were to do it, it must be done in a post processing step before display.
Kishore Nallan
10/29/2021, 1:35 PMAtleast now, it is possible to do this on the client side because words will be marked with <mark> tags.

10/29/2021, 1:36 PMAh, I get the relevance aspect but sometimes I want to return all lines containing "foo" from each doc
k
Kishore Nallan
10/29/2021, 1:36 PMYou can do it on the client side easily now. Split paragraphs into sentences, and in each sentence check for number of <mark> tags and rank sentences on number of occurrences and show top N.

10/29/2021, 1:48 PMI was concerned that doing it on the frontend might result in a nontrivial overhead (in the case of a collection with many long documents) and having it offered by the engine would be beneficial. But maybe this is a rare use case.

10/29/2021, 1:48 PMThanks for digging whether it's possible!

10/29/2021, 1:50 PMCertainly we can add an option for doing it, but just cautious about introducing too many new flags 🙂

10/29/2021, 1:51 PMYeah, makes sense
