problem with search

[ian.h.terrell]

Is there a good description of how to use the search field?

It seems fine for smallish strings, but the longer string we have the stranger the results seem.

Is there a limit to the length a query can be?

We are getting fewer results after we have added more OR values that should increase results.

I attached a text file with search strings and the number of results they got.

Thanks!

Ian

Hi Ian,

My guess is that your default search operator is AND, and the multi-word terms are being interpreted as eg. dc.subject.mesh:Fetal AND Nutrition AND .... OR dc.subject.mesh:Pregnancy ...., and so on - those additional words become regular search terms not tied to a field and using the default operator.

I had a go at wrapping the terms in " quotes in the demo DSpace 6.3 site but it seemed to break the query so I guess there is still some quote encoding or escaping issue going on?

If you have direct access to the Solr search service, could you try your queries there with the terms wrapped in double-quotes and see if the numbers look better?

Cheers

Kim
