Method Detail

andField

public MoreLikeThisOpenedMatchingContext andField(String fieldname)

Description copied from interface: MoreLikeThisOpenedMatchingContext

Add one field to the fields selected to match the content. An exception is thrown if the field are neither storing the term vectors nor physically stored. We highly recommend to store the term vectors if you plan on using More Like This queries.

Specified by:

andField in interface MoreLikeThisOpenedMatchingContext

Parameters:

fieldname - the name of the field

Returns:

this for method chaining

boostedTo

public MoreLikeThisOpenedMatchingContext boostedTo(float boost)

Description copied from interface: FieldCustomization

Boost the field to a given value Most of the time positive float: - lower than 1 to diminish the weight - higher than 1 to increase the weight Could be negative but not unless you understand what is going on (advanced)

Specified by:

boostedTo in interface FieldCustomization<MoreLikeThisOpenedMatchingContext>

Parameters:

boost - the boost value, it can be negative (advance)

Returns:

ignoreAnalyzer

public MoreLikeThisOpenedMatchingContext ignoreAnalyzer()

Description copied from interface: FieldCustomization

Advanced Do not execute the analyzer on the text. (It is usually a good idea to apply the analyzer)

Specified by:

ignoreAnalyzer in interface FieldCustomization<MoreLikeThisOpenedMatchingContext>

Returns:

an instance of T for method chaining

ignoreFieldBridge

public MoreLikeThisOpenedMatchingContext ignoreFieldBridge()

Description copied from interface: FieldCustomization

Do not try and find the field bridge nor apply the object / string conversion matching objects should be of type String in this case.

Specified by:

ignoreFieldBridge in interface FieldCustomization<MoreLikeThisOpenedMatchingContext>

Returns:

an instance of T for method chaining

toEntityWithId

public MoreLikeThisTermination toEntityWithId(Object id)

Description copied from interface: MoreLikeThisMatchingContext

Find other entities looking like the entity with the given id. Only the selected fields will be used for comparison.

Specified by:

toEntityWithId in interface MoreLikeThisMatchingContext

Parameters:

id - the identifier of the entity

Returns:
