I have found out a lot more information;
but, I still don't know why searching for method declarations never works,
and searching for method references only works sometimes.
I know that for every project in your workspace, it may be indexed (by
method name declarations and/or references at least).
That indexing is done by IndexManager.rebuildIndex.
I'm not sure when that actually happens.
I tried to force index rebuilding by deleting the files in the index
directory.
However, the flag createIfMissing was usually not set.

Hi Chuck,
DLTK Indexer uses structure parser to report types, method, fields, etc and references into index.
The we search we use MatchLocator and MatchLocator parser to match and report AST nodes. For method declaration search
MethodLocator class are used to match for pattern.
Could you please put breakpoints to following places:enterMethod
For indexing check:
1) SourceIndexerRequestor.enterMethod(MethodInfo methodInfo)
This method will be called then we index module and report keys into index.
You could also check here for references.
Then we search using Search( For example from search dialog):
2) MatchLocatorParser.parseBodies(MethodDeclaration)
This method will be called then we we start processing of module. Module will be processed if some keys are associated
to this module, then we build index.
3) MethodLocator.match(MethodDeclaration node, MatchingNodeSet nodeSet)
This method will be called then declaration are matched from MatchLocatorParser.
Also this method will add AST node to list of search matches.
4) MatchLocator.reportMatching(ModuleDeclaration decl)
This method will locate structure model element for each of matches.
Also you could look at our Ruby, Tcl implementations.
IQueryParticipant:
This is for extensibility only. You do not need to look at them.
Python:
Does search for method declarations not work in Example?
If you have reproducible example could you please create a bug in Eclipse bug tracker.
Best regards,
Andrei Sobolev.
