: q=reference:"4-1.2" : : the value is a text, but the following is indexed as a number (e.g.: : 004001002, where "4" becomes "004", and 1 becomes "001", and 2 "002"),
depnding on how you look at it, you could implment this as one of two plugins: 1) if you consider this a special form of query syntax, then you should implement it as a QParser -- ie: a RefrenceNumberQparser that it could be used with any field/fieldType/FieldType, regardless of wether it's ultimately backed by a TrieLongField or an IntField, etc... 2) if you consider this to be an special format of the underlying data, then you would implement it in the FieldType -- ie: by subclassing TrieLongField and calling it RefrenceNumberField and overriding methods like readableToIndexed (and optionally: things like indexedToReadable and toObject if you'd like to format the resulting data as "4-1.2" when you return it to the client) Practically i think the key decision maker is what sort of behavior you want to support if someone asks for something like "refrence:4" ... should that be equivilent to "4-0.0" (in which case you could implement this easily as a FieldType) or should it be a range query for everything in article 4, regardless of section and subsection? (in which case i would implement it in a QParser) -Hoss
