There are several topics intertwined with solutions you seek: There's parts of speech (PoS) tagging, reducing to Lemma form, identifying end of sentence, etc.

After having faced a similar learning curve, I put what I know into a lengthy document[0] written in 2018 based upon explorations over 2016-17. That will get you deployed and operational quickly by following just the final section. The first section explains key concepts using conventional ideas as the means of introducing NLP jargon. In between covers theory and practice for getting the most out of any tool you're likely to use in the end.

More general tools are probably available today, such as add-ons for Elasticsearch. I'd start looking there. Interesting items came up when searching ddg for: NLP elasticsearch.

There's also a pretty good book https://lingpipe-blog.com/2008/06/12/book-building-search-ap...

of course the more general tools available today notice applies in regard to this book as well.
