Add Advanced Term search about swate

[Freymaurer]

PR #32 added a stored procedure for advanced term search, just needs implementation in the app.

As written before i found the search by "startsWith", "contains" and "endsWith" not optimal. I now implemented my version with 4 variables:

• search term name for keywords
• substring that must exist in term name
• search term definition for keywords
• substring that must exist in defintion

I am always happy for new ideas on what this advanced search needs and i think we will come back to this issue after some user feedback. For now everything works fine and is implemented. Will do a PR to developer soon, then we can think about a minimal POC release.

When creating fullText indexes on Name,Accession, and definition, it is possible to query CONTAINS and FREETEXT on all three columns at once.

We propably should discuss on how to implement this correctly. In my opinion the "ends with query" will not be used. i cannot think of any situation i would search by how a term/definitions ends. But as we recently implemented a is_a directed search option, we should think about adding this option also to the advanced term search. Let me know what you think @kMutagene.
