Search Help

At the homepage, search Wyoming Inventors by Last Name, First Name, and/or City. The Advanced Search tool allows for a more in-depth query, using other variables to locate your information.

General Search Tips

  • Searches are not case sensitive, so capitalization is unnecessary;
  • All searches automatically retrieve both singular and plural forms of words;
  • Use quotes to search for a specific Phrase or name;
  • If you get large result sets, Narrow results using the “filters” box on the left side of the results page.

Keyword (Boolean) Search

(AND, OR, NOT, WITHIN, ADJ)

Boolean searches will find the exact keywords entered in the Search For box. To narrow the results of a search, words can be combined with Boolean operators (AND, OR, NOT, WITHIN, and ADJ) to retrieve relevant materials. To conduct more complex searches use Parentheses to combine sets of words and Boolean operators.

Boolean operators Description Example
AND retrieve a list of items where Word1 (Labor) and Word2 (Union) both appear in the text Labor AND Union
OR retrieve a list of items where either Word1 (Labor) or Word2 (Union) appears in the text Labor OR Union
NOT retrieve a list of items where Word1 (Union) but not Word2 (Pacific) appears in the text Union NOT Pacific
WITHIN retrieve a list of items where Word1 (Union) appears within N (1,2,3,4,etc) words of Word2 (Railroad) Union Railroad WITHIN 2
ADJ retrieve a list of items where Word1 (Pacific) and Word2 (Company) appear within N (1,2,3,4,etc) words of each other and Word1 must appear before Word2 in the results. Pacific Company ADJ 2
Complex Search pair multiple words with multiple Boolean operators to retrieve a list of items where all the words appear within close proximity to each other in one item (“coal miners”) and (labor AND union) and (strike OR boycott) WITHIN 50

Wildcard Search

Use wildcard characters (*, ?, [search expression], _, @, #, \, ^ ) to substitute part of a word, name, or number, or to search for multiple terms. Wildcards can be used in Concept or Boolean mode, in keyword search or field entries, in multiple words, and even multiple times in one word. See examples:

Wildcards Description Example Result
_ match one or zero characters colo_r color, colour
@ match exactly one alpha character gr@y gray, grey
# match exactly one numeric character #600 1600, 8600
\ take the next character literally, not as an operator name\@ptfs.com name@ptfs.com
* match anything or nothing scholar* scholar, scholarship
? match exactly one character wom?n woman, women
^ match any character except the next character 200[^7] 2006, 2008, 200G
[ ] search expression; can include a hyphen to indicate a range of letters or numbers; will match only one character within the brackets 200[6-8] 2006, 2007, 2008
