That works if you're looking for a specific girl, but not if you want isolate reports on girls in a specific area.
If it only crops up 50 times then maybe "Bolton" isn't the bestvexample but if you wanted to isolate reports for girls in Manchester as opposed to the whole of the North West it would be handy if you could limit the search to the Review section without including the discussion section
Yeah, that would be helpful. At least though when you see the results it is immediately apparent which ones are reviews (due to the large coloured rating) but obviously you have to scroll past a lot of the discussion posts. It's debatable whether it's best to search by most relevant (which will bring up more reviews with Bolton in the title but many of which can be quite old) or by newest/most recent which will show up any review thread which mentions Bolton (which may or may not be the actual subject/location of the review) but the ones that are relevant will be even more so because they're recent. Also, remember to set the maximum results to 200 (as there's more than just 50 or 100 posts which mention Bolton).
When it comes to Manchester, in some ways it could be even trickier to search because some people (myself included) only mention the specific area of Manchester (although I do usually mention Manchester as well when it's a more "obscure" location).
Also, I'd tend to be cautious about being too specific in searches because obviously you'll only get exactly what you searched for - this can be particularly problematic when searching for parlour reviews where abbreviations or slightly different spellings are used, e.g. Sandys, Sandy's, SS etc would all throw up slightly different results with some overlaps so it's wise to do multiple searches to ensure you find everything.
