Subject [jira] [Comment Edited] (NIFI-4234) The Filter in the Add Processor window should return valid results even if search terms do not exactly match tags

----------------------------------------------------

It seems the current simple regex match on processor tags doesn't fit for a bit more complex
use cases. 

Queries containing the tag separator char ({{,}}) should be treated separately. In this particular
case the query would be tokenized and behave like: "_database && rdbms_". This way
it makes sense to me, since you are being more specific by adding tags.

In this case the "_database rdbms_" query wouldn't work. Since tags like "_data science_"
exist, the space char can't be treated like a token separator.

I'm not sure an actual query language is needed.

> The filter field should be more forgiving.  For example, if you enter "database, rdbms"
you get 2 results (ConvertJSONToSQL and PutSQL processors).  I would think the following would
also return the same results, but you get none:
> "database,rdbms"
> "database rdbms"
> "rdbms, database"
