Tips for Searching SARC Documents
Search queries retrieve documents containing words or phrases provided by the user. The simplest query is based on a single word. For example, to find all documents that contain the word "wheat", simply type the word wheat in the search box;
and then either press [Enter] or click the [Search] button. All searches are case in-sensitive. Search words can be typed in upper and/or lower case letters.
Simple search queries will retrieve a maximum of 100 documents. More complex queries often are needed to retreive the desired information. For more complex queries, please read the following sections and examples.
Using Multiple Words in Searches
Multiple words are read as literal strings or phrases. For example, a search for the words;
will retreive only those documents containing the exact phrase "winter wheat". Documents containing the words "winter" and "wheat" either seperately or alone will not be retrieved. Use keywords (see below) to provide more control over the retreival of documents where the occurance of words or phrases in other combinations is desired.
Using Wildcards in Searches
Ending a search word with a single asterisk ( * ) modifies the search for words with the same prefix. For example, type;
to find all documents containing winter, winterhardiness, winterkill, and so on.
Ending a search word with two asterisks ( ** ) searches for all forms of a word. For example, type;
to find sink, sinking, sank, and sunk.
Using Reserved Keywords in Searches
The scope of a search can be modified by using one or more of the keywords AND, AND NOT, NEAR and OR. Keywords are case-insensitive and do not require capitalization.
AND - Use the keyword "AND" to retrieve documents that contain combinations of words or phrases. For example, to find all documents that contain both the words "winter" and "wheat" regardless of their order of occurance, write the following query:
Typing the ambersand character ( & ) is equivilent to using the keyword "AND" in searches.
AND NOT - Use the keywords "AND NOT" to exclude documents containing certain words or phrases from your search. For example, if you want to find all documents discussing wheat but not barley, write the following query:
NEAR - Search with the keyword "NEAR" rather than the keyword "AND" to prioritize the rank of documents for words close to each other. For example, both of these queries:
look for the words "winter" and "wheat" in the same document. When using the keyword "NEAR", the returned pages are ranked in order of proximity; the closer together the words are, the higher the rank of that page.
OR - The keyword "OR" finds all documents containing either one word or another, or both. For example:
Documents that contain either the word "winter" or the word "wheat", as well as documents containing both words, regardless of order, are retrieved.
Using Quotation Marks with Keywords in Searches
Place quotation marks around phrases containing keywords if you want the search to be literal. For example, the following query;
will literally look for documents containing the complete phrase "wheat and barley". If the same query is typed without the quotation marks;
all documents containing the words "wheat" and "barley", regardless of order, will be retrieved.
