2个数据集+文本索引的Fuseki配置：如何使用turtle文件？

Question

我们需要对数据进行索引，因为使用“filter（CONTAINS（））”的SPARQL查询对大型数据集（“bnf_text”）不起作用。因此，我为“bnf_text”建立了一个文本索引，下面是：Fuseki indexed（Lucene）文本搜索不返回任何结果（但我不得不修改turtle配置文件以使text:query工作）。

它工作，但我遇到了一个奇怪的问题“bnf_text”：同一查询不时返回一个超时，我在fuseki日志和apache日志中都看不到find error。

~~~~~~~~ 这里是我的问题:~~~~~~~~

• 我的配置文件有问题吗？
• 性能是否受两个数据集共存的影响？

~~~~~~~~下面是我安装的详细信息:~~~~~~~~

• 脚本中修改的Java内存限制fuseki-server:设置为--XMX4000M。
• SPARQL查询通过PHP EasyRDF库发送
• 我有2个配置文件:$fuseki_path/text_config.ttl+$fuseki_path/run/configuration/my_dataset.ttl
• 我使用以下命令运行fuseki-server:./fuseki-server--config text_config.ttl

## Initialize TDB --------------------------------

[] ja:loadClass "com.hp.hpl.jena.tdb.TDB" .
tdb:DatasetTDB  rdfs:subClassOf  ja:RDFDataset .
tdb:GraphTDB    rdfs:subClassOf  ja:Model .

## Initialize text query -------------------------------------
[] ja:loadClass       "org.apache.jena.query.text.TextQuery" .
# A TextDataset is a regular dataset with a text index.
text:TextDataset      rdfs:subClassOf   ja:RDFDataset .
# Lucene index
text:TextIndexLucene  rdfs:subClassOf   text:TextIndex .

## ---------------------------------------------------------------
## This URI must be fixed - it's used to assemble the text dataset.

<#indexLucene> a text:TextIndexLucene ;
