Definitely. Product catalog information as a whole doesn't change often. Price and availability does. With retail catalogs you often do a full reindex of the data in your master catalog and then run partials to account for price/availability if you don't do that in realtime using filters. Since the system of record is not the search index, Elastic is often not a good solution here.

Also, relevancy in retail is often influenced by other factors that cannot easily be implemented in Elastic. TFIDF/BM25 search is available in both platforms, but you may also weigh in other factors such as relationships with the vendor, stock on hand, or other ML techniques that are more easily implemented in SOLR.

I think a big reason is simply that Solr has been around a few years longer and most older sites would have been using that by the time Elasticsearch came along and never saw a good reason to go through a painful process of replacing one with the other.

These days, I would say there's very little that either product does that the other product can't do though obviously there are lots of strengths and weaknesses on both sides.
