SearchResult.TextMatchInfo

Kotlin |Java

public static final class SearchResult.TextMatchInfo
extends Object implements Parcelable

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

This class represents match objects for any text match snippets that might be present in SearchResults from a string 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 text 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,

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

TextMatchInfo.getFullText() returns "Test Name Jr."
TextMatchInfo.getExactMatchRange() returns [0, 4]
TextMatchInfo.getExactMatch() returns "Test"
TextMatchInfo.getSubmatchRange() returns [0, 4]
TextMatchInfo.getSubmatch() returns "Test"
TextMatchInfo.getSnippetRange() returns [0, 9]
TextMatchInfo.getSnippet() returns "Test Name"

Match-2

TextMatchInfo.getFullText() returns "Testing 1 2 3"
TextMatchInfo.getExactMatchRange() returns [0, 7]
TextMatchInfo.getExactMatch() returns "Testing"
TextMatchInfo.getSubmatchRange() returns [0, 4]
TextMatchInfo.getSubmatch() returns "Test"
TextMatchInfo.getSnippetRange() returns [0, 9]
TextMatchInfo.getSnippet() returns "Testing 1"
