How to use the MarkLogic thesaurus API on phrases?

Question

In Marklogic we can expand a search to include terms from a thesaurus as well as the terms entered in the search.

xquery version "1.0-ml";
import module namespace thsr="http://marklogic.com/xdmp/thesaurus" at "/MarkLogic/thesaurus.xqy";

cts:search(
doc("/Docs/hamlet.xml")//LINE,
thsr:expand(
    cts:word-query("weary"), 
    thsr:lookup("/myThsrDocs/thesaurus.xml", "weary"),
    (), 
    (), 
    () )
)

Question is how to support below cases :

• Apple AND Orange
• Apple NOT Orange
• Apple - Orange
• Apple + Orange
• form: 10-K
• co: Apple
• Apple Orange form:[10-K]
• “Apple and Orange”
• “Apple” Orange

Answer 1

I don't think thesaurus expansion is intended for these cases.

Instead, consider using the Search API and expanding the grammar to include variants on the boolean operators:

To map form: and co: to the same index, again, consider using the Search API and defining multiple constraints for the same index:

Answer 2

Use search:parse to parse the query string, yielding cts:query XML. Then use a recursive typeswitch function to walk the XML. Use thesaurus expansion on cts:word and cts:word terms.
