When searching for section numbers, you may find that many documents are returned which contain only a portion of the section number you searched for. Most section numbers use a hyphen or period to format parts of the section number. These characters are treated as whitespace characters by our search analyzer and as such, split the section number into several individual tokens.
Much like searching for dollar amounts, searching for sections will results in documents that appear to have only partial matches, though documents with full matches will still show near the top with the most relevance.
To work around this anomaly, simply force a phrase search using double quote. Below you will see a before and after of a sample search for section 13-258.
