I don't know if it already works like this, but:
When using some filtering option, like "at least 1 of my keywords must be present" if the first page of site/blog get's filtered because it does not contain any keyword, does the whole site show up as "already parsed"?
If so, I think it should be corrected, I mean some filters are at the domain level and some are specific to the single page.
A typical exampe is scraping a list with another program and feeding it to GSA, you might have several pages from the same blog, if the first one doesn't contain any keyword all the urls would be skipped, instead some other posts could contain your keywords.
These are the filters I can think of:
- domain PR -> domain level (whole site is filtered and becomes "already parsed")
- page PR -> page level (you should filter this page but not whole domain)
- keyword -> page level
- OBL -> page level
- bad words filter -> page level
- bad words in domain/url -> domain level (?)
