The page selector can be used to restrict the search area of the parsing pipeline.
You can specify either a number or a range, using the start: end syntax. Like for many other selectors, it is possible to use negative numbers to specify a page index starting from the end of a document.
Note: It is a very useful selector in terms of boosting performance.
For large documents, we recommend adding the page selector (or the boundary selector) as the first selector of the parsing pipeline, wherever it is possible and makes sense.
