Hi Erick,
thanks for your response.
Not that I know of. I presume that you want this to reduct typing
or some such. Your app could simply massage the query
that was typed, doing the appropriate substitutions before
parsing the query....
Well I found a much better solution which avoids "double parsing". I
created my own QueryParser by extending the existing. Then I identified
five methods to override:
getFieldQuery(String field,String queryText)
getFuzzyQuery(String field,String termStr, float minSimilarity)
getPrefixQuery(String field,String termStr)
getRangeQuery(String field,String part1, String part2, boolean inclusive)
getWildcardQuery(String field,String termStr)
In each of this methods I call my own method:
field = translateField(field);
before passing the values to it's super implementation.
And my translateField method uses a Hashtable for looking up field
aliases. It it finds an alias it returns it, otherwise the field is
returned without modification. Therefore I have my field aliases without
having to implement an own parser - thanks to the good OO-design of the
QueryParser class.
BTW: If someone wants to took onto the complete source just ask. I did
not want to attach/include them because of its size (most of the code
has been generated by Eclipse...)
