CSW converting query strings to lower case makes filter queries fail

[simonp]

Reported by t800t8:

I tried to find with literal 'OGC:WMS*' but the service return no result but it should return 2 results as expected.

Here is my filter query:

<Filter xmlns="​http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml">

<PropertyIsLike wildCard="*" singleChar="#" escapeChar="!"

matchCase="false">

<PropertyName>protocol</PropertyName> <Literal>OGC:WMS*</Literal>

</PropertyIsLike>

</Filter>

I had a look at this particular case (still interested to hear about the others Abdi!). The problem is that the wild card query text (in this case OGC:WMS*) is being converted to lower case by the lucene query builder in src/org/fao/geonetwork/search/LuceneSearcher.java (makeQuery method). This is unfortunate because the protocol field against which this query is being run in Lucene is not tokenized (which is correct) and the protocol strings are all in upper case.

Proposed fix is to remove the blanket toLowerCase in the makeQuery method and apply the Analyzer that goes with the field being queried to the text provided in Filter query. eg. in this case the protocol field is not tokenized/analyzed so it should not be changed by the query parser.
