Discovery: include word proximity in search results #869

Open pdpinch opened 8 years ago

pdpinch commented 8 years ago

in multi-word searches, is there a way we can weight search results higher when the words appear in close proximity?

Another approach to #866

@pwilkins does this make sense?

Yes, Elasticsearch supports proximity. We "simply" have to add proximity support to the tool chain that generates an index. (The tool chain is called an analyzer.) This article section provides a high-level description of how this feature works.

As @giocalitri mentioned in our f2f meeting, we should be prepared for this to create larger index files. Perhaps significantly larger.
