Search Buttons


Search Database - Use this button if you would like to search only the GrainGenes MySQL database. This is a general search that will return data associated with the general classes presented by the GrainGenes Database Browser.

Search Website - Use this button to search only the web pages that compose the GrainGenes website. No data from the database will be presented in the results.




Searching

Basic
- type in the word(s) for which you would like to search. Wildcard characters are not assumed in searches so partial words should not be used.

Example: "data" will return "data" NOT "database"

Wild Card - use * as the wildcard character for searches.  Allows for an expanded search using fewer characters.

Example: "data*" will return "data" AND "database"

Boolean - returns pages based on the Boolean operators used in the search field (e.g. "AND", "OR", "NOT")
Examples of correct expressions are: cat and dog, cat not dog, cat or (dog not nose).
Note that the operator not has the meaning of 'without'.



GrainGenes Search Page

This page presents the results obtained by pressing either the "Search Database" or "Search Website" buttons. The results page inlcudes an additional search field that includes more query options. This search form will only search the area selected by the previously used search button. This is not a refine search but a new search of all available documents.

Limit Search to:

Body and Title
- searches the body and title of all documents for matches

Just Title - searches only the title of all documents for matches
