Yonik Seeley commented on SOLR-218:
-----------------------------------
With regards to doing something like lowercasing wildcard queries, that should
be a per-field setting for Solr.
But as I stated here: http://www.nabble.com/case-sensitivity-tf3654523.html
I think Solr should figure out the right thing to do automatically.
The implementation should probably be a method on FieldType that handles
lowercasing (or otherwise manipulating) the wildcard query if necessary, or
perhaps throwing an exception if it's just not supported for that field type.

> Key: SOLR-218
> URL: https://issues.apache.org/jira/browse/SOLR-218
> Project: Solr
> Issue Type: Improvement
> Components: search
> Affects Versions: 1.1.0
> Reporter: Michael Pelz-Sherman
>
> The SolrQueryParser class, which extends Lucene's QueryParser class, does not
> provide any way of setting the various QueryParser properties via the solr
> config file (solrconfig.xml). These properties include:
> allowLeadingWildcard (Set to true to allow * and ? as the first character of
> a PrefixQuery and WildcardQuery)
> dateResolution: Sets the default date resolution used by RangeQueries for
> fields for which no specific date resolutions has been set.
> defaultOperator: Sets the boolean operator of the QueryParser.
> fuzzyMinSim: Set the minimum similarity for fuzzy queries.
> locale: Set locale used by date range parsing.
> lowercaseExpandedTerms: Whether terms of wildcard, prefix, fuzzy and range
> queries are to be automatically lower-cased or not.
> phraseSlop: Sets the default slop for phrases.
> useOldRangeQuery: By default QueryParser uses new ConstantScoreRangeQuery in
> preference to RangeQuery for range queries.
> This can be achieved by calling the setter methods for these properties in
> the SolrQueryParser constructor,
> public SolrQueryParser(IndexSchema schema, String defaultField) {
> super(defaultField == null ? schema.getDefaultSearchFieldName() :
> defaultField, schema.getQueryAnalyzer());
> this.schema = schema;
>
> setAllowLeadingWildcard(SolrConfig.config.getBool("query/setAllowLeadingWildcard"));
>
> setLowercaseExpandedTerms(SolrConfig.config.getBool("query/lowerCaseExpandedTerms"));
> }
> In addition, solr should not modify these values from the defaults provided
> by Lucene, as it currently does by calling setLowercaseExpandedTerms(false)
> in this method.
