Exact phrase search on very large text

[Mike Thomsen]

I need to be able to do exact phrase searching on some documents that are a
few hundred kb when treated as a single block of text. I'm on 4.10.4 and it
complains when I try to put something larger than 32kb in using a textfield
with the keyword tokenizer as the tokenizer. Is there any way I can index
say a 500kb block of text like this?

Thanks,

Mike
