Confused at choosing the best search engine

Question

I am currently using a custom Java search engine. This Java engine uses Lucene to index MySql records. There are several problems with the search engine:

1- Search results are inaccurate.

2- He does not use weighting algorithms to make the most suitable result from above.

3- It consumes a lot of memory.

4 It is very difficult to maintain for various reasons.

So what I need to do is use a ready-made search engine, commercial or open, which can seamlessly integrate with my system and solve my problems (as much as possible).

Could you give me options and where to look.

Thanks Wael
