| /** |
| * The Nexus indexer is a statefull facade that maintains state of indexing contexts. |
| * <p> |
| * The following code snippet shows how to register indexing context, which should be done once on the application |
| * startup and Nexus indexer instance should be reused after that. |
| * |
| * <pre> |
| * NexusIndexer indexer; |
| * |
| * IndexingContext context = indexer.addIndexingContext( indexId, // index id (usually the same as repository id) |
| * repositoryId, // repository id |
| * directory, // Lucene directory where index is stored |
| * repositoryDir, // local repository dir or null for remote repo |
| * repositoryUrl, // repository url, used by index updater |
| * indexUpdateUrl, // index update url or null if derived from repositoryUrl |
| * false, false ); |
| * </pre> |
| * |
| * An indexing context could be populated using one of {@link #scan(IndexingContext)}, |
| * {@link #addArtifactToIndex(ArtifactContext, IndexingContext)} or |
| * {@link #deleteArtifactFromIndex(ArtifactContext, IndexingContext)} methods. |
| * <p> |
| * An {@link org.apache.maven.index.updater.IndexUpdater} could be used to fetch indexes from remote repositories. |
| * These indexers could be created using the Indexer CLI command line tool or |
| * {@link org.apache.maven.index.packer.IndexPacker} API. |
| * <p> |
| * Once index is populated you can perform search queries using field names declared in the {@link ArtifactInfo}: |
| * |
| * <pre> |
| * // run search query |
| * BooleanQuery q = new BooleanQuery(); |
| * q.add(indexer.constructQuery(ArtifactInfo.GROUP_ID, term), Occur.SHOULD); |
| * q.add(indexer.constructQuery(ArtifactInfo.ARTIFACT_ID, term), Occur.SHOULD); |
| * q.add(new PrefixQuery(new Term(ArtifactInfo.SHA1, term)), Occur.SHOULD); |
| * |
| * FlatSearchRequest request = new FlatSearchRequest(q); |
| * FlatSearchResponse response = indexer.searchFlat(request); |
| * ... |
| * </pre> |
| * |
| * Query could be also constructed using a convenience {@link NexusIndexer#constructQuery(Field, SearchExpression)} |
| * method that handles creation of the wildcard queries. Also see {@link DefaultQueryCreator} for more details on |
| * supported queries. |
| * |
| * @see IndexingContext |
| * @see org.apache.maven.index.updater.IndexUpdater |
| * @see DefaultQueryCreator |
| * @author Jason van Zyl |
| * @author Tamas Cservenak |
| * @author Eugene Kuleshov |
| * @deprecated Use {@link Indexer} instead. |
