Which live search wiki engine to choose?

Question

Knowledge base

It is required to place a database of old printed magazines on the Internet. I originally planned to do it on Confluence, but it turned out to be too voracious. Now I'm thinking about a wiki engine or an analogue, which option can I consider? Of the requirements, preferably php + MySQL, live search.
The content itself will be of three types:
- Issue. Fields: articles, pages in issue, year, authors
- Article. Fields: author, pages in issue, number, year. Title in English and Russian, annotations (Perhaps the full text of the article will be added in the future)
- Authors. Information about the author, photo, list of his articles in issues (number, year, pages)

Answer 1

Wikimedia uses ElasticSearch. It all depends on the amount of data to search. You will have to store most of the index in memory, so the capacity should be sufficient. If resources are limited, it will still work, but only slowly.
In general, ElasticSearch is a great thing!
