[VuFind-Tech] Search

[Osullivan L. <L.O...@sw...>]

Hi Folks,

I've been a query regarding searching from one of our subject librarians which I was hoping to address via searchspecs.yaml but which may be impossible to resolve because of the solr snowball filter. Here's the query:

Say I’m looking for a book, “Foundation of Mathematics” If search for

Foundation mathematics

I get zillions and relevance is not helpful.

If I search for

“foundation of mathematics”

It is still prioritizing “Foundations of mathematics” – if I put quotes, I would expect it to search for literally that string, not variations?

I’ve come across this quite a few times, is there any way to refine its search mechanism for phrases in quotes?

An analysis of the query reveals that the final tokenisation is "foundat" "of" and "mathemat" in the title field - even with this being the case, why do values with s take precedence over values without?

The title_full_unstemmed field looks more promising - would I be better off boosting that?

Cheers,

Luke
