Not really, no. Some parts of search (Internet) have been cornered/solved by big players (e.g. Google), but many other parts (e.g. search in Intranets) are still an open problem. No one has found a solution that's as simple as PageRank for Intranets. No one has found a solution for the "the author of half of these documents is the intern who wrote the template"-problem and many other things. There are good products out there, but a "Google for Non-Internet" is still far away.
p.s.: All the bad searches on the various products I use or the websites of some companies make me almost want to get back into search. Because even for things that ARE solved in the technical sense there seems to be no "out of the box" solution or people would use it.
edit: To expand a bit - all the search solutions I've seen which weren't for Internet search were more or less bespoke, so you needed a project to get something decent. Sure, you can install a plain Lucene/Solr, but Lucene/Solr cannot understand the way your data works, which parts are important or if you want to show results which are older further down (or not!). They have decent defaults for the "common case", but you have to tune them for every customer/installation for good results and that makes it non-scalable. And being scalable without effort is usually one of the requirements people have for something to be "solved".
