A drop-down list is used to determine how the system should interpret the query. Your choices are:
- All of these words
- Any of these words
- As a phrase
- Natural Language
- As a Boolean query
The default is: All of these words.
All of these words - This option allows you to enter a single word, a group of words, phrases enclosed in quotation marks, and combinations of words and phrases. With this option selected, the system will find and accept ONLY those documents that contain ALL the words in the query textbox. Therefore, the AND operator is assumed. In the returned documents, the query words may be together, but not necessarily — the only requirement is that they all be contained in the document.
Phrases are groups of two or more words.
For example:
"Social Security Administration"
"the land of the free"
"what you see is what you get"
Note: Do not place single words in quotes — they are not phrases.
Any of these words -
As above, you can enter a single word, a group of words, phrases enclosed in quotation marks, or combinations of words and phrases. Documents containing any one or a combination of more than one of the entered terms and phrases will be returned. This option is the same as using the OR operator. The following query returns all documents that mention Abbott or Costello or both.
Abbott OR Costello
As a phrase -
Use this selection if you are entering two or more words that will constitute a phrase. DQM will accept ONLY those documents that contain at least one occurrence of the phrase words precisely in the order in which you entered them as a query. The example below will return documents with the phrase:
War and Peace
United States of America
Note: There is no need to include quotation marks; selecting this option automatically makes DQM treat all query words as a phrase.
Natural Language -
Natural Language (also known as "free text") queries can take several forms from questions and sentences to a listing of key words or a listing of key words separated by commas. When a Natural Language query is used, the system removes those words having no search value, such as prepositions, articles, common verbs, adjectives, etc. The remaining terms are then processed as the query and used to determine whether or not returned documents are pertinent to your harvest. The examples below are Natural Language queries:
"What is the capital of France?"
"The rain in Spain falls mainly in the plain"
As a Boolean query -
With this option, you can enter a standard Boolean query. The supported Boolean operators are:
AND
OR
AND NOT
NEAR
