Library Research: Your Search Strategy
Now, you are ready to phrase a search statement. You must phrase it so a database will know whether you want all your search terms, either one or the other, or to eliminate instances where a particular word or phrase exists:
Procrastination AND college students |
Database searches for instances where procrastination AND college students appear |
College students OR university students |
Database searches for instances where EITHER the words guns OR firearms appear. Both CAN appear or just one of them. |
Depression NOT great |
Database finds all instances where depression appears but ONLY WHEN the word great does not (say all you kept getting was articles on the Great Depression of the 1930’s) |
Notice that the search statements depend on an OPERATOR to basically give the database a command as to how it should perform its search based on the terms entered: (AND, OR, NOT). This is pertinent.
Once you have come up with a SEARCH STATEMENT, you are now ready to perform searches on the Library Catalog, our periodicals databases, and our other databases.
When using search engines to search the World Wide Web, search statements you enter are slightly different. Take notice:
+"college students" +grades +procrastination |
A "plus" sign is used to tell the database that the words MUST appear within the web pages you are searching. |
+Depression -great |
A "minus" sign is used to tell the database that the word depression MUST appear but ONLY WHEN great does not. |
"colleges students” “Self-defeating behavior” “techniques to overcome procrastination” |
In most search engines, you MUST surround your phrase with quotation marks. Most search engines treat each word separately. If there were no quotes, the search engine will likely find pages that EITHER have the words college OR students And anywhere these words appear on a web page, meaning a lot of non-relevant results! |
