A better default collation isbinary. This is the fastest collation for comparisons and can use standard indexes. It also makes comparisons of column values immune to session settings, which are used in thelegacy method for case-insensitive search. This is often critical for correct results. I...
In addition, Oracle SES search attributes are case-insensitive, and therefore all attributes are converted to lowercase when used in XML format. For example, suppose the raw XML result data is as follows. <result> <eqdatasourcetype>WEB</eqdatasourcetype> Oracle Secure Enterprise Search <url> ...
3)创建一个叫'xmlgroup'的interMedia Text section group , 添加 Name和Dept tag到section group中。(Caution: in XML, tag names are case-sensitive, but tag names in section groups are case-insensitive) BEGIN ctx_ddl.create_section_group ('xmlgroup', 'XML_SECTION_GROUP'); ctx_ddl.add_zone_se...
The Search tab consists of the Relevancy, Suggested Links, Suggested Content, Alternate Words, and Source Groups subtabs. These pages help you improve search quality. Search - Relevancy Make important documents easier to find with relevancy boosting. Oracle SES lets you influence the order of docum...
The above example will return 2 because it is counting the number of occurrences of 't' in the string. Here we did not specify a match_parameter value, the REGEXP_COUNT function will perform a case-sensitive search which means that the 'T' characters will not be included in the count....
·positionis a positive integer indicating the character ofsource_charwhere Oracle should begin the search. The default is 1, meaning that Oracle begins the search at the first character ofsource_char. ·occurrenceis a positive integer indicating which occurrence ofpatterninsource_charOracle should se...
A search now based on WHERE name=’ZIGGY’ will automatically perform a case-insensitive searchwithoutthe need to modify the application to use specific functions. For a full demo, seeUse Linguistic Indexes Demo. However, before you rush out and start using Linguistic Indexes to possibly simplify...
CASE_INSENSITIVE_SEARCH Emulate the same behavior of MSSQL with case insensitive search. If the value is citext it will use the citext data type instead of char/varchar/text in tables DDL (Ora2Pg will add a CHECK constraint for columns with a precision). Instead of citext you can also ...
