Match and Search are not synonyms, I suggest
Change "Match Type" to "Search Type",
Change "Match All" to "Search All (and)"
Change "Match Any" to "Search Any (or)"
I'd still prefer different modifier keys to select between All (and) and Any (or) and so would my linguistics and economics 'lay person' research colleagues.
Its the sort of thing one wants to make a decision about at the time the multi-tag search feature is being used. Wouldn't be so bad if one could see the current setting, but as it is one has to look behind Alter Tag Browser, and then behind Match Type, then remember than 'all' will give one an 'and' and that 'any' will give one an 'or', and then the phone rings...
