Question

我的Java Google App Engine的本地实例似乎很好地索引搜索文档，但在运行搜索时开始抛出异常。包含代码段和例外。 TIA！

搜索代码：

QueryOptions options = QueryOptions.newBuilder()
            .setLimit(500)
            .build();
    String queryString = searchStr;
    Query query = Query.newBuilder().setOptions(options).build(queryString);

    IndexSpec indexSpec = IndexSpec.newBuilder().setName(projectName + "Search").build(); 
    Index index = SearchServiceFactory.getSearchService().getIndex(indexSpec);

    Results<ScoredDocument> results = null;

    try {

        results = index.search(query);

    } catch (SearchException e) {

    }

例外：
