Searching the CAS Botany Collection Database

General Remarks

The query form enables you to retrieve specimen records by virtually any combination of fields present in the database. Wildcard characters for text fields are % which represents zero or more characters, and _ which represents exactly one character.

Query feedback. The query parameters entered on the form are summarized in query language at the top of every result page. Read the query statement to be sure that the query being processed is what you intended. Some browsers have a tendency to "remember" parameters from previous queries. Press the Clear button between queries to clear previously used parameters.

Number of records. The number of records retrieved by the query is reported immediately after the query feedback (near the top of the page) while the results are formatted. If the number returned is much larger than you expected or want to wait for, press the Stop button on your browser to cancel the query. You can create a more restrictive query by adding additional criteria to the form.

Downloading of datasets. Search results can be downloaded as a tab-delimited text file by clicking the button in the upper left of any search results page. The file will be either the brief record dataset or the full record dataset, depending on which one you are currently viewing.

Input Types On The Form

Text Box

a text box

A simple text box accepts a string of alpha-numeric characters and compares it against values in the database. The input string must match the entire value, unless wildcard characters are used. Wildcard characters are the percent sign (%) and the question mark (?). The percent sign matches zero to many characters, whereas the question mark matches one and only one character. For example, searching the species field with rhino% will match "rhinoceratus" and "rhinostoma".
 

Single-Select List Box

 

[any] 1st choice 2nd choice 3rd choice a single-select list box

A single-select list box displays all the values that occur in the database, but allows only one value to be used in a given query. The default value, "<any>", causes the field to be ignored.
 

Multi-Select List Box

1st choice 2nd choice 3rd choice 4th choice a multi-select list box

A multi-select list box displays all the values that occur in the database and allows multiple values to be used in a given query. Use Ctrl-Click to toggle individual selections on and off; i.e., hold the Control key down (Windows), or the Command key (Macintosh) when you click on a value. Note, clicking a value without holding down the control key (i.e., a simple click) clears all other selections in the list box and leaves the most recently clicked value as the only selection. Note also that some browsers "remember" selected values between queries even though the selected values are not visible in (i.e., have scrolled off) the list box. Press the Clear button to clear the form.
