First, I want to make sure when you say "TTL", you're talking about documents being evicted from the documentCache and not the "Time To Live" option whereby documents are removed completely from the index.
The time varies with the number of new documents fetched. This is an LRU cache whose size is configured in solrconfig.xml. It's pretty much unpredictable. If for some odd reason every request gets the same document it'll never be aged out. If no two queries return the same document, when "cache size" docs are fetched by subsequent requests. The entire thing is thrown out whenever a new searcher is opened (i.e. softCommit or hardCommit with openSearcher=true) But maybe this is an XY problem. Why do you care? Is there something you're seeing that you're trying to understand or is this just a general interest question?
