This has the advantage of making available all of the useful Google search functions. We can search for a phrase, exclude a word, find any combination of words, search with wildcards and so on. These logical functions are commonly known as Boolean operators. They are described in some detail in Google's search help pages which should be read by anyone intending to do serious searching.
These examples are based on the Hansard advanced search form.

Make the search even more specific by adding another term (Google treats upper and lower case equally).
Change the year to compare results to a previous year:
Search engines rarely give absolute results. At most the results are approximations and will always require a bit of common sense to interpret. Google is one of the best search tools and is currently the most used. As part of its continuing improvement Google works with a dictionary of synonyms and may attempt to help with your search by looking for synonyms to the search terms as well as for the terms themselves.
Google's "artificial intelligence" (AI) and can make for some interesting browsing.

Notice that "red light" and "red signal" are now treated as valid search terms by the Google synonym dictionary.
If you need an exact phrase you may assist the AI by enclosing the terms in quotes or by entering them in the exact wording field in the advanced search form.
Google's default behaviour is to look for all the words (ie: the default operator AND is implied between each word). To search for one or both of several words or phrases, you can use the OR operator (type 'OR' in ALL CAPS).
Finally, do remember to use the Hansard special indexes. Every sitting week a speech index is prepared for each member. There is also a subject index. The indexes are cumulated at the end of each year.
