Search function returns incorrect count in LMS 7.9 and 7.9.1

Hi,

maybe someone can help with the search function of the LMS.(7.9 and also 7.9.1) I tried to use the search (tag based) described here:

for instance Genre
http://htmlpreview.github.io/?https:...pi.html#genres
or Title
http://htmlpreview.github.io/?https:...pi.html#titles

for instance:
titles 0 50 tags:al search:cry\x0A (search for „cry“ in Titles)

There's just one result in my database however the tag parameter: "count" returns 3.

Any idea? It should be one to process the results correctly.

Thanks

S
