Basic and Advanced Search Queries

Queries: Basic and advanced search


SEARCH QUERY is a complex of search terms, their chosen form and target, and operators that connect them. With a query you express your information needs in a database in such a way, that system can perform a logic search.

QUERY FORM means the interface of a search engine. In the form, you place the search terms and choose the operators in order to formulate the query.

Names of the search types might vary from database to database. The basic idea is either to search in a quick and rough way: Basic search; or to search with more detailed and tailored way: Advanced search.

Basic search


BASIC SEARCH –type form contains one box where you type the whole query.




Operators and parentheses, if needed, must be typed by yourself.

Usually, if you don’t type anything between search terms, there will be the AND-operator by default.







Advanced search


ADVANCED SEARCH –type form allows you to make more sophisticated queries. It also makes the use of operators structured.


It is easy to make a logic query if you think that one line in query form is equivalent to one search concept.

All the alternative terms referring to the same concept are written to the same line. Between the alternative terms, you must type the OR-operator by yourself.

The next concept is written to the next line. Lines (concepts) are connected with AND-operator.

With Advanced search, it is easy to select the fields to be searched for.

This is the basic model of Advanced search with is valid in all databases:
