SQL (Structured Query Language) is one of the most powerful database languages in the world. SQL databases use tables with rows and columns to maximize search speed. This particular search engine uses the Boolean Operator
AND by default which means
that if you use multiple search words or phrases in multiple fields the search engine will locate all records which contain all the keywords in your query.
Examples:
You may search by search word or phrase. For instance, let's say you want to find every mention of McCarty Street. If you type in the word McCarty in the Description field and click on Search you would find every occurence of:
McCarty Street
E. McCarty St.
McCarty and Lafayette
McCarty Street Exit
West McCarty
However, if you type in the phrase "East McCarty St." (enclosed with quotes) you will find only records with that exact phrase. Your search would find only records with:
East McCarty
Your search would miss E. McCarty or even East McCarty Street because you used the abbreviation St. instead of Street in the search.
In addtion to searching for "exact phrases" you can use other Google-like enhancements like adding + or - signs in front of search words. For instance, searching for:
Your search will produce
records which contain
McCarty but DO NOT contain any mention of the word
Dunklin. You can also use wildcard designations with
* and
?.
