Search tips

These tips will help you search NBS Building Regulations for the Building Regulations Approved Documents.


At its simplest, a query can be just a word or a phrase. But with the tips on this page, you can expand the focus of your query to give you more complete results. The following tips will get you started with basic queries and help you maximise your search results.

  • Look for words with the same prefix. Type key* to find key, keying, keyhole, keyboard, and so on.
  • Search for all forms of a word. Type sink** to find sink, sinking, sank, and sunk.
  • Search with the keyword NEAR, rather than AND, for words close to each other. Both system and manager and system near manager, look for the words system and manager on the same page. With NEAR, the returned pages are ranked in order of proximity: The closer together the words are, the higher the rank of that page.
  • Refine your queries with the AND NOT keywords to exclude certain text from your search. If you want to find all instances of surfing but not the Net, type surfing AND NOT the Net.
  • Add the OR keyword to find all instances of either one word or another. Type Abbott OR Costello to find all pages that mention Abbott or Costello or both.
  • Put quotation marks around keywords if you want the search to take them literally. If you type "system near manager" the search will look for the complete phrase system near manager. If you type the same query without the quotation marks, system near manager will retrieve all documents containing system and manager.
  • Use free text queries if you want to enter queries using natural language. The search will examine your query, extract nouns and noun phrases and construct a query for you. With free text queries you can enter any text you want, from a proper question, to a string of words and phrases, without worrying about the query language. For example, if you type "Where is Part M?" the search will create a query for you automatically and begin the search. Note that when you're using free text queries, the regular query language features are disabled and keywords such as AND, OR, and NEAR are interpreted as normal words.
