How to understand - the problem is in the request for obtaining data, or in the code?

Question

PHP

it happens that in a project sometimes the search results on the site do not meet expectations. You kill hours climbing in the debugger in all kinds of classes, but it turns out that the bad request that went to get data in Solr is to blame. How to get around that, so as not to climb through all the methods, but immediately understand that the fault is in the request that went into the solr, and not look for some kind of if, which is "most likely to blame"?
