    copied!<p>i know how to implement it,using field assist and search pattern, but the mechanism each time triggers a new search. I am not sure, how the mechanism is implemented in Open Type for example ( i think with indexes). How to use this cache to make in time classpath search</p> <p>This almost my entire solution. Each time a call createProposalData </p> <pre><code>private TreeSet&lt;String&gt; data; private SearchParticipant[] participants = new SearchParticipant[] { SearchEngine .getDefaultSearchParticipant() }; private SearchPattern pattern; private IJavaProject prj; private JavaSearchScope scope; private SearchEngine searchEngine = new SearchEngine(); private SearchRequestor requestor = new SearchRequestor() { @Override public void acceptSearchMatch(SearchMatch match) throws CoreException { String text = getText(match.getElement()); if (text != null) { data.add(text); } } public String getText(Object element) { ... } }; public ProposalEngine(IJavaProject prj) { super(); this.prj = prj; scope = new JavaSearchScope(); try { scope.add(prj); } catch (JavaModelException e) { // } } public Collection&lt;String&gt; createProposalData(final String patternText) { data = new TreeSet&lt;String&gt;(); try { pattern = getPatternForSeach(patternText); searchEngine.search(pattern, participants, scope, requestor, null); } catch (Exception e) { // skip } return data; } protected SearchPattern getPatternForSeach(String patternText) { return SearchPattern.createPattern(patternText, IJavaSearchConstants.CLASS_AND_INTERFACE, IJavaSearchConstants.DECLARATIONS, SearchPattern.R_CAMELCASE_MATCH); } </code></pre>
