Detailed Description

An attribute to store query properties of persistent search collections.

This attribute is attached to persistent search collections automatically when creating a new persistent search with SearchCreateJob. Later on the search query can be changed by modifying this attribute of the persistent search collection with an CollectionModifyJob.

Example:

const QString name = "My search folder";
const QString query = "...";
 
Akonadi::SearchCreateJob *job = new Akonadi::SearchCreateJob( name, query );
connect( job, SIGNAL(result(KJob*)), SLOT(jobFinished(KJob*)) );
 
MyClass::jobFinished( KJob *job )
{
  if ( job->error() ) {
    qDebug() << "Error occurred";
    return;
  }
 
  const Collection searchCollection = job->createdCollection();
  ...
 
  // now let's change the query
  if ( searchCollection.hasAttribute<Akonadi::PersistentSearchAttribute>() ) {
    Akonadi::PersistentSearchAttribute *attribute = searchCollection.attribute<Akonadi::PersistentSearchAttribute>();
    attribute->setQueryString( "... another query string ..." );
 
    Akonadi::CollectionModifyJob *modifyJob = new Akonadi::CollectionModifyJob( searchCollection );
    connect( modifyJob, SIGNAL(result(KJob*)), SLOT(modifyFinished(KJob*)) );
  }
  ...
}

Member Function Documentation

isRecursive()

bool PersistentSearchAttribute::isRecursive

(

)

const

Returns whether the search is recursive.

Since

4.13

Definition at line 62 of file persistentsearchattribute.cpp.

isRemoteSearchEnabled()

bool PersistentSearchAttribute::isRemoteSearchEnabled

(

)

const

Returns whether remote search is enabled.

Since

4.13

Definition at line 72 of file persistentsearchattribute.cpp.

queryCollections()

QList< qint64 > PersistentSearchAttribute::queryCollections

(

)

const

Returns IDs of collections that will be queried.

Since

4.13

Definition at line 43 of file persistentsearchattribute.cpp.

queryString()

QString PersistentSearchAttribute::queryString

(

)

const

Returns the query string used for this search.

Definition at line 33 of file persistentsearchattribute.cpp.

setQueryCollections() [1/2]

void PersistentSearchAttribute::setQueryCollections

(

const QList< Collection > &

collections

)

Sets collections to be queried.

Parameters

collections

List of collections to be queries

Since

4.13

Definition at line 48 of file persistentsearchattribute.cpp.

setQueryCollections() [2/2]

void PersistentSearchAttribute::setQueryCollections

(

const QList< qint64 > &

collectionsIds

)

Sets IDs of collections to be queries.

Parameters

collectionsIds

IDs of collections to query

Since

4.13

Definition at line 57 of file persistentsearchattribute.cpp.

setQueryString()

void PersistentSearchAttribute::setQueryString

(

const QString &

query

)

Sets the query string to be used for this search.

Parameters

query

The query string.

Definition at line 38 of file persistentsearchattribute.cpp.

setRecursive()

void PersistentSearchAttribute::setRecursive

(

bool

recursive

)

Sets whether the search should recurse into collections.

When set to true, all child collections of the specific collections will be search recursively.

Parameters

recursive

Whether to search recursively

Since

4.13

Definition at line 67 of file persistentsearchattribute.cpp.

setRemoteSearchEnabled()

void PersistentSearchAttribute::setRemoteSearchEnabled

(

bool

enabled

)

Sets whether resources should be queried too.

When set to true, Akonadi will search local indexed items and will also query resources that support server-side search, to forward the query to remote storage (for example using SEARCH feature on IMAP servers) and merge their results with results from local index.

This is useful especially when searching resources, that don't fetch full payload by default, for example the IMAP resource, which only fetches headers by default and the body is fetched on demand, which means that emails that were not yet fully fetched cannot be indexed in local index, and thus cannot be searched. With remote search, even those emails can be included in search results.

Parameters

enabled

Whether remote search is enabled

Since

4.13

Definition at line 77 of file persistentsearchattribute.cpp.
