Detailed Description

Search query.

Definition at line 26 of file core/query.h.

Member Enumeration Documentation

◆ SortingOption


The results are returned in the most efficient order.

They can be returned in any order.


The results are returned in the order the SearchStore decides should be ideal.

This criteria could be based on any factors. Read the documentation for the corresponding search store.


The results are returned based on the explicit property specified.

The implementation of this depends on the search store.

Constructor & Destructor Documentation

◆ Query() [1/3]

Query::Query ( )

Definition at line 47 of file core/query.cpp.

◆ Query() [2/3]

Query::Query ( const Term & t)

Definition at line 52 of file core/query.cpp.

◆ Query() [3/3]

Query::Query ( const Query & rhs)

Definition at line 58 of file core/query.cpp.

Member Function Documentation

◆ addCustomOption()

void Query::addCustomOption ( const QString & option,
const QVariant & value )

Adds a custom option which any search backend could use to configure the query result.

Each backend has their own custom options which should be looked up in their corresponding documentation

Definition at line 176 of file core/query.cpp.

◆ addType()

void Query::addType ( const QString & type)

Add a type to the results of the query.

Each Item in the result must contain one of the types. This is generally used to filter only Files, Emails, Tags, etc

One can add multiple types in one go by separating individual types with a '/'. Eg - "File/Audio".

Please note that the types are ANDed together. So searching for "Image" and "Video" will probably never return any results. Have a look at KFileMetaData::TypeInfo for a list of type names.

◆ addTypes()

void Query::addTypes ( const QStringList & typeList)

Definition at line 80 of file core/query.cpp.

◆ customOption()

◆ setDateFilter()

void Query::setDateFilter ( int year,
int month = -1,
int day = -1 )

Filter the results in the specified date range.

The year/month/day may be set to -1 in order to ignore it.

Definition at line 133 of file core/query.cpp.

◆ setLimit()

void Query::setLimit ( uint limit)

Only a maximum of limit results will be returned.

void Query::setSearchString ( const QString & str)

Set some text which should be used to search for Items.

This contain a single word or an entire sentence.

Each search backend will interpret it in its own way, and try to give the best possible results.

Definition at line 108 of file core/query.cpp.

Definition at line 155 of file core/query.cpp.

◆ setSortingProperty()
