Can i do a full-text search where each word has location metadata?

Elastic Stack Elasticsearch

I'm trying to build a text search from voice to text, each word should have a metadata position something like start: 54s; end: 57s.

Metadata shouldn't be indexed but only returned with results. Is that possible? I'd appreciate some advice on how to do it.

You'd need to figure this out before sending to Elasticsearch, there's nothing native that could calculate this.

Thank you for the replay, currently I can get text and position from audio.

My current idea is to make a regular text search then use a custom highlighter to get the text position. With the position query an SQL database for a location in audio.

I'm wondering if I could do the whole thing natively with Elastic

Elasticsearch cannot do the sort of merge/join with the words and the timings, you may need to do that in your client.

But you could put both sets of data into Elasticsearch then you've got a quick data store to leverage at least :slight_smile:
