Hello,
I have implemented with success a keyword-based search feature with MyFaces
/ Tomahawk. Tomahawk has an Ajax-based component:
JSF page:
<t:div styleClass="menuLevelFloatDiv">
<t:panelGrid columns="3">
<s:inputSuggestAjax styleClass="menuLevelItem" charset="utf-8"
autoComplete="false"
suggestedItemsMethod="#{searchKeywordBean.getSuggestedKeywords}"
style="width=130px;"
maxSuggestedItems="10"
value="#{searchKeywordBean.userKeyword}"/>
<t:commandButton styleClass="menuLevelItem"
value="#{msg.searchButton}"
onclick="dojoWaitDialogKeyWord.show()"
action="#{searchKeywordBean.lookup}"/>
<t:commandButton styleClass="menuLevelItem"
value="#{msg.queryButton}" action="query"/>
</t:panelGrid>
</t:div>
<%-- wait dialog box --%>
<s:modalDialog dialogId="dojoWaitDialogIDKeyWord"
dialogVar="dojoWaitDialogKeyWord"
dialogAttr="bgColor='white' bgOpacity='0.5' toggle='fade'
toggleDuration='250'"
styleClass="dojoWaitDialog" hiderIds="okID">
<h:graphicImage styleClass="waitImage" value="images/wait.gif"/>
</s:modalDialog>
Backing Bean:
/**
* Suggested keywords for Ajax listbox
*/
public List<String> getSuggestedKeywords(String userPrefix, Integer
maxSize) {
List<String> foundKeywords = new ArrayList<String>();
String userPrefixUC = userPrefix.toUpperCase();
..............................................

And I do call a Lucene index here.
Best,

You can get the information pretty quickly by using a
WildcardTermEnum (NOT query). Especially if you
terminate after some number of characters....
