Text search on JS

Please advise if any easy library for fast text search on the client (browser) side. What you need: there is a list of the elements that have id and row. We must look on the line (and substrings) and, for example, to return id of the element.
Now I've done it with regulyarok, but it is not very bright at high volumes. I would like a complete solution that builds an index and it is looking for.
