WebGlimpse SearchTips for searching the LTER Site Data Catalogs
If you are having trouble finding matches for a given topic or keyword, be sure to try all possible synonyms. The keywords used in the site catalogs are managed by the individual sites (and often the individual investigators) and are therefore not uniform. See the listing of catalog entries by keywords for a demonstration of all the possible variations. You may also want to make sure that the search is not case sensitive, and that it allows for partial matches and misspellings.
Boolean operators can also be used to expand (or narrow) your search. To perform an "AND" search, enter both strings you wish to search for separated by only a semicolon (";"). For example, the following search will find all entries that contain both the word "snow" and the word "melt".
To perform an "OR" search, enter both strings you wish to search for separated by only a comma (","). The following example will find all the entries that contain either the word "snow" or "melt" (or both). If you wish to exclude a string from a search, an "AND NOT" can be performed by preceeding the string you wish to exclude with a semicolon and tilde (";~"). In this case, the following will find all the entries that contain the word "snow" but do not contain the word "melt". Curly brackets ("{}") can be used to perform multiple boolean operations following logical semantics. For example, the following search will return all the entries that have the word "snow" but do NOT have either the word "melt" OR "depth" (or both). While the following search will return all the entries with the word "snow" that do NOT have both the words "melt" AND "depth".
