Search Type Information:
Natural Language Searches
Natural Language matches are geared towards bringing back one correct entry. They are intended to return the closest match to the question the user has posed, rather than every possible entry that matches the question.

Natural Language relies on a context in order to better understand what you are searching for. If you've entered a phrase or a full sentence, the natural language processor will parse the question and take into account which word acts as the verb, the noun, the subject, etc. It is more precise than a Keyword match—it will bring back less entries, but they will be a tighter match to the actual question asked. However, if you only enter 1-2 words, there is not enough of a context for Natural Language to match correctly.
Keyword Searches.
While QuikFAQ was designed for Natural Language queries, it can also search on keywords. This means that instead of entering a full question in the search field, you can select the 'Keyword' radio button, and enter a keyword or two in the search field. These types of searches tend to be more generic, meaning that not all articles returned will be relevant. For example, a Keyword inquiry could be used to get all of the entries that contain the word “Intercom” at least once, just by entering this word alone. As mentioned above, keyword search results are less precise than Natural Language results, but with certain types of content, such as technical, Keyword Searches may provide better matches.

Although the single-word queries described above are already very useful, QuikFAQ’s Keyword mode also allows for more complex expressions to be used as the criterion. Such expressions can be formed using the simple connectors AND, OR and NOT. The best way to explain this is using examples. In the following table, if the query expression is what is shown in the left-hand column, the right-hand column shows what entries will be included in the result set.

It is important to note that AND is always implied when using Keyword mode in QuikFAQ, and in many other search engines as well. This means that if you want to see entries using both words, you do not need to add AND. However, if you want to match to either word, you must use OR in your query. (Notice that “AND” has a higher precedence than “OR”.)

Expression  Will hit…
system requirements An inquiry like "system requirements" will return the same set of entries as the query "system AND requirements", but the entries will be sorted to give priority to those that best satisfy "system BEFORE requirements".
system OR requirements All entries containing either the word “system” or the word “requirements” (or both).
 NOT system All entries but the ones containing the word “system”
NOT (system AND requirements) All entries except those hit by the first query above.
requirements AND NOT
system		 Entries that contain the word “requirements” but do not also contain the word “system”.
Door OR CCTV
AND requirements 		All entries that contain the word “Door”, plus entries that contain both the word “CCTV” and the word “requirements”.
(Door OR CCTV)
AND requirements		 Entries that contain the word “requirements” and either the word “Door” or the word “CCTV” (or both).

For any word in a Keyword inquiry you can substitute the wildcard character ‘*’ to replace some portion of
the word. The wildcard character will match anything. 
Auto-Detect
QuikFAQ offers a new search option: Auto-Detect. When Auto-Detect is turned on, QuikFAQ evaluates the  inquiry and determines whether a Natural Language or a Keyword search would be more effective in finding accurate matches, and returns the results accordingly. Auto-Detect enables you to retrieve more accurate information without worrying about question types or the necessity of following detailed inquiry instructions.
