Query for tag field search

[ludvig-sandstrom]

Hi!
I'm trying to execute a tag field search with ftSearch, but I fail to understand how to implement it correctly. I tried to look up examples, but failed to find one. Could anyone provide a simple example?
I know the pure redis syntax and have tried to translate that into a query ( FT.SEARCH [index-name] "tag:{value}" ) but have so far failed miserably. I guess that the querystring should still be the value, and suspect the tag should be defined in a filter (addFilter) or similar, but none of my attempts have so far worked out.
Really grateful for any assistance.

Hopefully following tests would help.

Perhaps you need to do @tag:{value} with an @.

It was worse than that....built the tag value and managed to get an empty string to build it from in the first of my tests....so all stupidity....
Thanks again!

[ludvig-sandstrom]

Thanks a lot! Probably should've been able to guess that, but you made it a lot easier!
