minus in keyword

[liefra]

There are difficulties with keywords which do contain one or more minuses, for instance: "Fisheries - low income"

These keywords do show up in the advanced search keywords popup, but a search results in zero results.

We haven't tested any other Lucene special characters.

The affected keywords can be queried with the Lucene tool Luke, using a

org.apache.lucene.analysis.KeywordAnalyzer

Below are logging debug messages, showing a raw Lucene query:

DEBUG geonetwork.search  - Lucene Query: keyword:Fisheries - low income
DEBUG geonetwork.search  - Lucene Query: keyword:Fisheries - low income
DEBUG geonetwork.search  - Lucene Query: _op0:1
DEBUG geonetwork.search  - Lucene Query: _op0:0
DEBUG geonetwork.search  - Lucene Query: _op0:1 _op0:0
DEBUG geonetwork.search  - Lucene Query: _isTemplate:n
DEBUG geonetwork.search  - Lucene Query: +(keyword:Fisheries - low income) +(_op0:1 _op0:0) +_isTemplate:n

I checked in 2.4.3 assigning "Fisheries - low income" keyword to some metadata records and seem found them correctly.

Possibly was fixed with new search improvements
