Everyday I do a search for YAOI on PBS.  Lately the search results for posted books are not complete.  

If I do a general search under the term YAOI for posted books, it shows THREE books posted, including one book that is on my bookshelf. I have two issues with these search results.

1. I have TWO books on my bookshelf tha should be coming up in these search results,  not one. 
2. If I pull up all the books with a yaoi tag, there are actually SEVENTEEN posted books, not three!  And both of the books on my BS show up in these results.  So the search feature is NOT showing all available books.

Is anyone else having the same problem with getting complete search results???? OR is it just me?

If you mean "La Esperanca, Volume 1", it doesn't show up because it does not have YAOI in the title or elsewhere in the record.  The book search feature does not look at tags -- it looks at the bibliographic information only.  This is why searching for YAOI and looking at the books tagged YAOI bring different results.
