Here's the deal.
While searching for new novels to read by looking up novels that share a specific tag is good, it is however not enough in my opinion.
I think that it would be very helpful finding new novels one might be interested in reading by allowing us to look up more than one tag at the same time.
Essentially, this is a request for an Advanced Search option to allow us to select which tags we're looking for and/or which ones we want to exclude from our search.
I'm bringing this up because I don't find the search options here to be of much help. As a result, I had stopped looking up stories here, instead only checking out the ones that are being advertised to see if I'd like them or not.
However, recently there was a certain writing contest that drew my attention (#135 Female Lead - World of the Undead!). I intended to go through the contest entries while the contest page was available, but I suddenly got quite busy in the past week or so, and as a result I wasn't able to. Sadly, the contest page for that one is no longer available. I thus resorted to looking up new novels via tags, but the ones I'm personnally interesting in this time are those that share the "undead" tag and the "female-lead" tag. Here lies the problem. I can only search via one tag, and as a result I have to go through many novels that don't fit my requirement (sharing the two tags mentioned above) and it's easy to miss some of the ones I'm looking for among the ones I'm not interested in when it comes to this search.
Therefore, to reiterate, I believe that adding the option for more complex novel search with tags would be beneficial to the overall experience of the site and app users.
