Indexing and Search Operation
Indexing is used by GroupDocs.Search for Java to collect data, as well as store and parse it for accurate and efficient search operations. GroupDocs.Search for Java uses such Indexes frequently for performing search.
- Create Index: Create Index folder and add/index documents to that folder.
- Load Index: Load an existing Index.
- Add Documents to Index: Add documents to existing Index, asynchronously.
- Update Index: Update existing Index, whenever a document is modified, added or deleted. This keeps search results up to date.
Perform Wild Card Search - Java
// Creating index Index index = new Index("c:\\MyIndex"); // Adding documents to index index.addToIndex("c:\\MyDocuments"); // Searching for words 'affect' or 'effect' in a document with 'principal', 'principle', 'principles', or 'principally' SearchResults results = index.search("?ffect & princip?(2~4)");
Merge Multiple Indices to Improve Search Efficiency
GroupDocs.Search for Java API provides the feature to merge multiple indexes into a common index. For an index which is modified frequently, several delta indexes are created. This approach however, makes the search performance slow. GroupDocs.Search for Java overcomes this bottle-neck by creating one common index through merging various delta indexes. This common merged index contains all the information of the merged delta indexes. This approach keeps the delta indexes unchanged while remarkably improving the search efficiency. You can configure various functionalities to further tweak this process.
