• Match All
• Match None
• Match Phrase Prefix
• Match Phrase
• Match
• Multi-Match

Match All

You can use ElasticScoutDriverPlus\Support\Query::matchAll() to build a query that matches all documents:

$query = Query::matchAll();

$searchResult = Book::searchQuery($query)->execute();

Match None

You can use ElasticScoutDriverPlus\Support\Query::matchNone() to build a query that matches no documents:

$query = Query::matchNone();

$searchResult = Book::searchQuery($query)->execute();

Match Phrase Prefix

You can use ElasticScoutDriverPlus\Support\Query::matchPhrasePrefix() to build a query that matches documents, which contain the words of a provided text in the same order as provided:

$query = Query::matchPhrasePrefix()
    ->field('title')
    ->query('My boo');

$searchResult = Book::searchQuery($query)->execute();

Available methods:

• analyzer
• field
• maxExpansions
• query
• slop
• zeroTermsQuery

analyzer

analyzer is used to convert the query text into tokens:

$query = Query::matchPhrasePrefix()
    ->field('title')
    ->query('My boo')
    ->analyzer('english');

$searchResult = Book::searchQuery($query)->execute();

field

Use field to specify the field you wish to search:

$query = Query::matchPhrasePrefix()
    ->field('title')
    ->query('My boo');

$searchResult = Book::searchQuery($query)->execute();

maxExpansions

You can use maxExpansions to specify maximum number of terms to which the last provided term of the query value will expand:

$query = Query::matchPhrasePrefix()
    ->field('title')
    ->query('My boo')
    ->maxExpansions(50);

$searchResult = Book::searchQuery($query)->execute();

query

Use query to set the text you wish to find in the provided field:

$query = Query::matchPhrasePrefix()
    ->field('title')
    ->query('My boo');

$searchResult = Book::searchQuery($query)->execute();

slop

Use slop to define the maximum number of positions allowed between matching tokens:

$query = Query::matchPhrasePrefix()
    ->field('title')
    ->query('My boo')
    ->slop(0);

$searchResult = Book::searchQuery($query)->execute();

zeroTermsQuery

You can define what to return in case analyzer removes all tokens using zeroTermsQuery:

$query = Query::matchPhrasePrefix()
    ->field('title')
    ->query('My boo')
    ->zeroTermsQuery('none');

$searchResult = Book::searchQuery($query)->execute();
