I'm a long-time BearShare user, but recently decided to give LimeWire a try and I've got a couple questions that I couldn't find answers for in either the FAQ's or the forums:

1) I've found that when I do a "repeat search" for a given artist/album/... under the Audio filetype, I get results that include non-audio files. What's going on?;

2) In BearShare, all searches automatically use "AND" as the operator, and there is a filter option that allows for only exact matches to the search terms to be shown in the results. Is there anything similar in LimeWire? Does LimeWire allow boolean operators [AND, OR, NOT] in searches?

Thanx in advance for any info.
