## Search JavaDoc Package

### Entry Points

{@link SearchDocAction} registered in module layer.

### Control Flow

    performAction() toFind
        IndexSearch UI button_actionPerformed
        JavadocSearchEngine[Impl]
            foreach javadoc fs
                javadocSearchType = fs.getJavadocSearchType()
                javadocSearchType.getSearchThread(toFind)
                IndexSearchThread (Jdk12SearchThread[_japan])
                    insertDocIndexItem()
        JavadocSearchEngine[Impl] callback (presenting them in UI)

### Projectization Tasks

DocFileSystems must be found in project resources. Define javadoc resources lookup criteria. Mimics classpath lookup. (Library ref FileObjects has something in their lookup. the something is provided by JavaDocVolumeProvider.) How do I list project resource PMs. In project resource (descriptor) containers.
