Re: Find documents contained in search term
[In reply to]

Can't see how you could do it with standard queries, but you could
reverse the process and use a MemoryIndex.
Add the single target phrase to the memory index then loop round all
docs executing a search for each one. Maybe use PrefixQuery although
I'd worry about performance. Try it and see.
But if you're just doing string comparison
for each doc {
if target.startsWith(doc.text) {
// match
}
}
might be easier.
