High Code Java API to Index & Search Documents

GroupDocs.Search for Java is an on-premise Java API to help indexing document content & metadata, perform searches (boolean, faceted, fuzzy, Homephone) & custom text extraction, apply search filters, and highlight results.

Search & Index Java On-premise API Features

Indexing API Features

Create search index, apply index settings, & subscribe to index events.
Supports indexing documents from file, stream, or a data structure.
Merge multiple search indexes into one.
Support is available for:
- additional fields
- regular characters (separators & letters)
- blended characters (these special characters are indexed as separators as well as letters, e.g. hyphen)
- characters indexed as a whole word
- character replacement during indexing
- custom text extractors
Index files protected with password
Provides the compact and metadata index options.
Supports different level of compression to save extracted text in index.
Ability to filter documents during indexing.
Option to delete indexed paths from index.
While indexing, convert all characters to lowercase or remove diacritics from text using Character replacement.
Ability to specify desired set of characters as letters.
Implement the support for a custom text extractor and then use that custom extractor for indexing.
Delete or remove desired documents from the search index.
Remove or delete indexed folders & files from the Index.
Mark indexed documents with text labels without re-indexing.
Filter documents during the search via applied document attributes.
Apply various types of filters while indexing, such as:
- Creation Time Filter (i.e. skip files created earlier/later than a certain date, or outside the provided date range)
- Modification Time Filter (same as Creation Time Filter but works on the document modification date)
- File Path Filter (apply regex to skip the files with full paths not matching the specified pattern)
- File Length Filter (specify lower/upper bound, or the range of acceptable file length in bytes)
- File Extension Filter (only files matching the list of specified file extensions will be indexed)
- Logical NOT Filter (invert the logic of an internal filter)
- Logical AND Filter (composite filter that requires all internal filters to succeed)
- Logical OR Filter (composite filter that requires at least one internal filter to succeed)
Rename any indexed document without requiring it to reindex during the update
Add additional fields to indexed documents to associate more metadata.
Ability to save the document text in the Index.

Searching API Features

Supports various types of searches, such as:
- Boolean Search: – Supports AND, OR, NOT operators. – Combine multiple Boolean search quries to compose comlex quries.
- Case Sensitive Search: Considers uppercase & lowercase characters as distinct.
- Date Range Search: Searches based on provided date range in specified date format.
- Faceted Search: Searches only within specified fields instead of whole document.
- Fuzzy Search: Search that detects wrong spellings words correctly using fuzzy logic.
- Homophone Search: Search for words which are similar in sound (pronunciation) to the searched word.
Fetch the text of indexed documents in the HTML format.
Apply various filters while searching documents, such as:
- File Path Filter (apply regex to fetch the files with full paths matching the specified pattern)
- File Extension Filter (returns the files matching the list of specified file extensions)
- Attribute Filter (returns the files with whom the specified attributes are associated)
- Combined Filters (apply composite filters AND, OR, NOT to compose complex queries)
After the search the found resultant words & phrases within the document content can be highlighted.
Enable the keyboard layout correction option to replace the unsupported keyword characters with the actual characters.
Search for different word forms, such as, noun, adjective, forms of verbs etc.

Search Dictionary Management API Features

Various types of dictionaries can be used & managed, such as:
- Alias Dictionary
- Alphabet Dictionary
- Character Replacements Dictionary
- Document Passwords Dictionary
- Homophone Dictionary
- Spelling Corrector
- Stop Word Dictionary
- Synonym Dictionary
- Word Forms Provider

Sample Java code to use the Blended Characters in Search Indexing

String indexFolder = "c:\\MyIndex\\";
String documentFolder = "c:\\MyDocuments\\";

// Creating an index in the specified folder
Index index = new Index(indexFolder);

// Setting hyphen character type to blended
index.getDictionaries().getAlphabet().setRange(new char[] { '-' }, CharacterType.Blended);

// Indexing documents from the specified folder
index.add(documentFolder);

// Searching in the index
SearchResult result1 = index.search("Elliot-Murray-Kynynmound");
SearchResult result2 = index.search("Elliot");
SearchResult result3 = index.search("Murray");
SearchResult result4 = index.search("Kynynmound");
