Query Modifiers


Introduction
—  Query modifiers are query words that have special meaning to Google. Typically these operators modify the search in some way, or even tell Google to do a totally different type of search.
—  Query modifiers are used to retrieve data stored in the archive. They are used with sampling and calculation modes to get a specific data set. The following are the available Historian demand modifiers.
—  Query modifiers, also called WHERE components in JReport, are the clauses in WHERE in SQL-select statements. Selected SQL statements are called queries in JReport. Both query and query modifiers are stored in the catalog and the query modifier is stored independently in the catalog (not related to queries). When executing a report, JReport creates the SQL statement based on the query used in the report and can replace the WHERE clause in the SQL statement if there is a modified query modifier.
—  The query modifier in the catalog can be hidden in two formats: structure and string. Groups of conditions are stored in the structure format. The query modifier consists of multiple groups of states and groups are connected by a logical operator. Each condition consists of many conditions and the conditions are also linked by a logical operator. Each condition consists of a left-hand expression, the relationship operator and a correct expression. The query modification text is saved in the format of the string.
—  Use the following commands in your search
◦      Define
◦      All in title
◦      Al lin url
◦      Site
◦      File type
            Define     
—  The query will provide a definition of the words you enter after it, gathered from various online sources. The definition will be for the entire phrase entered.
—  (example digital library) Google will include all the words in the exact order you typed them)
All in title  
·        If you start a query with (all in title] Google will restrict the results to those with all of the query words in the title. For instance (all in title: digital library) will return only documents that have both "digital" and "library" in the title.
All in url
·        If you start a query with [all in url] Google will restrict the results to those with all of the query words in the URL. For instance (all in url digital library) will return only documents that have both "digital" and "library" in the URL.
Site
·        If you include (site) in your query, Google will restrict the results to the given domain. For instance, UK  site:www.ippmedia.com will find pages about JK within www.ippmedia.com. (Law site:edu) will find pages about law within .edu urls. [Com, org, gov, net, ac.tz, etc]
File type
·        Specify a type of document to search. Example; doc, pdf, ppt, mp3, mpg, mp4 etc
Related      
·        The query [related:] will list web pages that are "similar" to a specified web page.  For instance, [related:www.google.com] will list web pages that are similar to the Google homepage.
