SearchResult.MatchInfo

Kotlin |Java

public static final class SearchResult.MatchInfo
extends Object implements Parcelable

java.lang.Object
↳	android.app.appsearch.SearchResult.MatchInfo

This class represents match objects for any snippets that might be present in SearchResults from a query. Using this class, you can get:

the full text - all of the text in that String property
the exact term match - the 'term' (full word) that matched the query
the subterm match - the portion of the matched term that appears in the query
a suggested text snippet - a portion of the full text surrounding the exact term match, set to term boundaries. The size of the snippet is specified in SearchSpec.Builder.setMaxSnippetSize(int)

for each match in the document.

Class Example 1:

A document contains the following text in property "subject":

"A commonly used fake word is foo. Another nonsense word that\u2019s used a lot is bar."

If the queryExpression is "foo" and SearchSpec#getMaxSnippetSize is 10,

MatchInfo#getPropertyPath() returns "subject"
MatchInfo#getFullText() returns "A commonly used fake word is foo. Another nonsense word that\u2019s used a lot is bar."
MatchInfo#getExactMatchRange() returns [29, 32]
MatchInfo#getExactMatch() returns "foo"
MatchInfo#getSubmatchRange() returns [29, 32]
MatchInfo#getSubmatch() returns "foo"
MatchInfo#getSnippetRange() returns [26, 33]
MatchInfo#getSnippet() returns "is foo."

Class Example 2:

A document contains one property named "subject" and one property named "sender" which contains a "name" property.

In this case, we will have 2 property paths: sender.name and subject.

Let sender.name = "Test Name Jr." and subject = "Testing 1 2 3"

If the queryExpression is "Test" with SearchSpec#TERM_MATCH_PREFIX and SearchSpec.getMaxSnippetSize() is 10. We will have 2 matches:

Match-1

MatchInfo#getPropertyPath() returns "sender.name"
MatchInfo#getFullText() returns "Test Name Jr."
MatchInfo#getExactMatchRange() returns [0, 4]
MatchInfo#getExactMatch() returns "Test"
MatchInfo#getSubmatchRange() returns [0, 4]
MatchInfo#getSubmatch() returns "Test"
MatchInfo#getSnippetRange() returns [0, 9]
MatchInfo#getSnippet() returns "Test Name"

Match-2

MatchInfo#getPropertyPath() returns "subject"
MatchInfo#getFullText() returns "Testing 1 2 3"
MatchInfo#getExactMatchRange() returns [0, 7]
MatchInfo#getExactMatch() returns "Testing"
MatchInfo#getSubmatchRange() returns [0, 4]
MatchInfo#getSubmatch() returns "Test"
MatchInfo#getSnippetRange() returns [0, 9]
MatchInfo#getSnippet() returns "Testing 1"

Fields

CREATOR

Added in API level 35

public static final Creator<SearchResult.MatchInfo> CREATOR

Public methods

getExactMatch

Added in API level 31

public CharSequence getExactMatch ()

Gets the exact term of the given entry that matched the query.

Class example 1: this returns "foo".

Class example 2: for the first MatchInfo, this returns "Test" and, for the second MatchInfo, this returns "Testing".

Returns
`CharSequence`	This value cannot be `null`.

getExactMatchRange

Added in API level 31

public SearchResult.MatchRange getExactMatchRange ()

Gets the MatchRange of the exact term of the given entry that matched the query.

Class example 1: this returns [29, 32].

Class example 2: for the first MatchInfo, this returns [0, 4] and, for the second MatchInfo, this returns [0, 7].

Returns
`SearchResult.MatchRange`	This value cannot be `null`.

getFullText

Added in API level 31

public String getFullText ()

Gets the full text corresponding to the given entry.

Class example 1: this returns "A commonly used fake word is foo. Another nonsense word that's used a lot is bar."

Class example 2: for the first MatchInfo, this returns "Test Name Jr." and, for the second MatchInfo, this returns "Testing 1 2 3".

Returns
`String`	This value cannot be `null`.

getPropertyPath

Added in API level 31

public String getPropertyPath ()

Gets the property path corresponding to the given entry.

A property path is a '.' - delimited sequence of property names indicating which property in the document these snippets correspond to.

Example properties: 'body', 'sender.name', 'sender.emailaddress', etc. For class example 1 this returns "subject"

Returns
`String`	This value cannot be `null`.

getPropertyPathObject

Added in API level 34

public PropertyPath getPropertyPathObject ()

Gets a PropertyPath object representing the property path corresponding to the given entry.

Methods such as GenericDocument#getPropertyDocument accept a path as a string rather than a PropertyPath object. However, you may want to manipulate the path before getting a property document. This method returns a PropertyPath rather than a String for easier path manipulation, which can then be converted to a String.

Returns
`PropertyPath`	This value cannot be `null`.
