Lucene query syntax for taxonomy searchs

Hi, I've got a taxonomy called Location. Taxonomy terms are indexed as Location-id. The raw indexed representation of a content item with a Location Taxonomy field set to a value with two ancestors (/58/56/59) might look like this:

Location-id 59
Location-id 56
Location-id 58

However, the query Location-id:59 doesn't return anything. Nor does Location-id:59 56 58.

I've wondered if this is because they are numeric not strings, but in any case, can anyone offer guidance regarding the syntax to query indexed taxonomy terms?

I've solved my own issue. In order to develop the appropriate queries within Orchard, I had been testing them in Luke (Lucene Index Toolbox). According to
  1. Untokenized fields are best added directly to queries, and not through the query parser. If a field's values are generated programmatically by the application, then so should query clauses for this field. An analyzer, which the query parser uses, is designed to convert human-entered text to terms. Program-generated values, like dates, keywords, etc., should be consistently program-generated.
I think this has something to do with why my queries failed in Luke, but searching on the taxonomy term id using SearchBuilder.WithField() worked perfectly.
