Search - make keyword search less fuzzy

[chouseknecht]

From @bcoca "just a question, if i search for something and it does not match anything ... I'm i supposed to get everything? seems like the search is really fuzzy, asdf returns many pages ..."

You should not get everything. In the case of ‘asdf’, I get 83 roles. And yes, that seems silly. In this instance it should not return anything, imho.

The ‘fuzziness’ is driven specifically by the way the index is built via django haystack. The edgengram analyzer has a min_gram value of 2. It’s tokenizing the search value by two chars and the text being searched by 2 chars. So in this case I would guess that ‘as’ can be found in all 83 roles. I could probably override the ElasticsearchBackend class and move the edgengram min_gram up to 3. That might be more sane.

So I think the work here is to bump the min_gram param in the index to 3.
