Hi ... I have just made an all files search for Mustang. 289 results. Note I am using LW4.10.0 which has no junk filter. Another thing is that on the latest Limewire there is a built in filter which eliminates apparent files which are in fact URls to any number of web sites. I do not know if these show in the count, but I know the files don't show up. This may be an explanation.
Also check that your media panel on the left does not just have one type selected.
Most of the results are mp3 and there is of course a famous song with Mustang in the title ..lots of them
What I was alluding to was this:
In video .. there are 119 results 8 showing 1 source, 3 showing 2 sources, 1 showing 3 sources and 2 showing 51 sources ( those last ones are undoubtably junk)
Add them all up and you get 119 results but only 14 different files
When you show all files in the search window, do you see 21/926 I do think that the URL files mght be includes in the large number but I'm not 100% sure.
