Question

我试图使用modeshape进行全文搜索。我对基于lucene指数的排名结果特别感兴趣。这是我的存储库配置

 "indexProviders": {
        "lucene": {
            "classname": "lucene",
            "directory": "${user.home}/repository/indexes"
        }
    },
    "indexes": {
        "textFromFiles": {
            "kind": "text",
            "provider": "lucene",
            "nodeType": "nt:resource",
            "columns": "jcr:data(BINARY)"
        }
    },

我注意到在指定位置创建了一个lucene索引。我将10-15个带有不同出现的搜索词的filesc添加到存储库中，并尝试使用一些单词进行搜索。我打印得分如下所示

        QueryManager querymgr = session.getWorkspace().getQueryManager();
        String query = "SELECT file.* FROM [nt:hierarchyNode] as file LEFT JOIN [nt:resource] as data ON ISCHILDNODE(data , file) WHERE "
                + "contains(data.*, '" + searchText + "')";

        Query createQuery = querymgr.createQuery(query, Query.JCR_SQL2);
        QueryResult result = createQuery.execute();     

        RowIterator rows = result.getRows();
        while(rows.hasNext()){
            Row nextRow = rows.nextRow();
         LOGGER.info("score : {}", nextRow.getScore());
        }

但是，所有结果的分数始终为1.0。还尝试了一个更简单的查询而没有加入...

SELECT data.* FROM [nt:resource] as data WHERE contains(data.*, 'searchterm')

但没有运气

使用带有modeshape的Lucene排名全文搜索结果
