At this point, you've learned the essentials of searching in Solr, from request handlers to the full query syntax, to DisMax, joins, geospatial, and more. We spent a lot of time on the query syntax because you'll see the syntax pop up in several places across Solr, not just in the user's query. Such places include filter queries, delete queries, boost queries, facet queries, embedded within certain function queries, and query warming (discussed in later chapters).

The subject of searching continues in the next chapter with a focus on relevancy/scoring matters. This starts with an explanation of Lucene/Solr's scoring model, and then various tools Solr gives you to influence the score, such as function queries, which are also useful in sorting and filtering.
