Boolean Query

qksearch supports boolean connectors to help form your search query more accurately. Usually there is no need to use boolean query unless you are looking for something very specific and rare. You can use the following boolean connectors:

Tip: better use our Advanced Search interface for a quicker and easier way.
 

+     using a + (plus sign) in front of a keyword (search word) tells qksearch to make sure this word must be present in results.

Example: +football
(this will ensure that the word football must be present in results)
 
 
-     using a - (minus sign) in front of a keyword (search word) tells qksearch that this word should not be present in results or be given negative priority.

Example: holiday -expensive
(this will ensure that the word expensive should not be present in results when the word holiday should be present)

Example: +holiday -expensive
(this will ensure that the word expensive should not be present in results when the word holiday must be present)
 
 
""     using double quotes ( "" ) around a phrase (or word combination) tells qksearch that this the phrase (or word combination) must be present in results as entered (case insensitive).

Example: "pc games"
(this will ensure that the word combination pc games be present in results)

Example: "pc games" -new
(this will ensure that the word combination pc games be present in results when the word new should not be present)
 
 
AND     using AND between keywords (search words) tells qksearch to make sure that both words must be present in results. This AND connector is case insensitive, so you can use either AND or and interchangeably.
Important: you must leave at least 1 space between the AND connector and your keywords.

Example: cheap AND loan
this will ensure that both cheap and loan must be present in results.
This is identical to: +cheap +loan   (less typing)
 
 
NOT     using NOT in front of a keyword (search word) tells qksearch to make sure that both words should not be present in results. This NOT connector is case insensitive, so you can use either NOT or not interchangeably.
Important: you must leave at least 1 space between the NOT connector and your keywords. You should not use this connector in front of the first keyword (search word); with in a multi-word query only.

Example: food NOT cuisine
this will ensure that both food be present in results but the word cuisine should not be present in results.
This is identical to: food -cuisine   (less typing)
 
 
domain:     use this connector to restrict results within a specific domain (or site).

Example: xbox domain:microsoft.com
(this will try to find documents about xbox from microsoft.com site/s)

Example: java domain:sun.com
(this will try to find documents about java from sun.com site/s)
 
 

Creating more complex boolean queries:

You can create complex boolean queries using all or any of the above mentioned connectors. Here are some examples:

Example-1:
food "easy recipe" -chinese
this will try to find documents that contains the word food, the phrase easy recipe but does not include the word chinese.

Example-2:
"ps2 console" "special offer"
this will try to find documents that contains the phrases ps2 console and special offer. If you are really interested in special offer you could try:
"ps2 console" AND "special offer"
(the AND connector will try to make sure both phrases are given highest priority)
