Basic Search : Enter one or more words to search for records that contain all of those words in any order e.g. smoking health
Boolean Search : Use the operators OR, AND, NOT or NEAR between words to create more complex queries. Tip for advanced searchers: using parentheses within a search box to enforce order of operations will not work in <odesi>. Instead, place each of your 'concepts' onto a different line.

Phrase Search : Surround phrases in quotes e.g. "health care costs"
Refine : Use the lists of of values that appear to the left of your search results to limit your search to specific keywords, geographic areas, and survey methods
Wildcard : Use a * or ? to expand your search to include all words that begin with the letters you type. ? matches exactly one character, while * matches any number of characters. E.g. he? will match only words like hem and hen, while he* will match he, hem, help, hello, etc.
Stemmed search : The system automatically performs a "stemmed search", which searches for all words with the stem you typed. This is based on word meaning, not spelling. E.g. searching for running will automatically return run, running, and ran. Note that if you use a wildcard (described above), word stemming no longer occurs. If you do not want word stemming to occur, use a phrase search instead.
