GAVC search: inconsistent results when searching by GAVC

Hello,

GAVC search giving inconsistent results. When trying to search for the artifact dgm.aek.cache:jcp_rfd:0.0.1-20160209 , we get completely inconsistent results depending on input in the search fields.

If I search for (Artifact ID = jcp_rfd) the search works and shows this artifact. OK.
If I search for (Artifact ID = jcp_rfd) the search works and shows this artifact. OK.
If I search for (Artifact ID = jcp_r*), the search returns my artifact, but also two others which ID is simply "jcp" - this shouldn't match.
If I search for (Artifact ID = jcp_*), the search returns many artifacts which ID does not even contain "jcp", like JavaRuleEngine and aggregator.
If I search for (Group ID = *dgm.aek.cache), the search returns my artifact. OK.
If I search for (Group ID = dgm.aek.cache), the search returns no result, even though this is the exact group ID of my artifact.
If I search for (Artifact ID = jcp_rfd, Version = *), the search returns my artifact. OK.
If I search for (Artifact ID = jcp_rfd, Version = 1), the search returns no result.
If I search for (Version = 0.0.1-2016*), the search returns no result
If I search for (Version = 0.0.1), I see some results, but my own package is not here.

And so on, and so on. GAVC search is not working as expected, Can you check and fix it?
