我在CentOS 7.3.1611(Core)上安装了DSE 5.1,solr 6.0.1。并且UIMA在eclipse中为我的注释器项目配置。
我正在关注Solr文档: https://wiki.apache.org/solr/Solr4UIMA
使用UIMA创建的项目有一个简单的注释器来获取人员名称,在UIMA的CAS Visual Debugger中已经正常工作。并且jar已经在solr lib目录中创建并复制(DSE_HOME / solr / lib),这里也是用于集成uima的solr的jar(SOLR_HOME / contrib / uima / lib,SOLR_HOME / contrib / uima / lucene-lib ,SOLR_HOME / dist / solr-uima-version)。
我在cassandra中创建的表是:
CREATE TABLE uima_solr.person_annotator (
id int PRIMARY KEY,
apellido text,
nombre text,
nombrecompleto text,
solr_query text,
uimaname set<text>
solr核心使用架构:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<schema name="autoSolrSchema" version="1.5">
<types>
<fieldType class="org.apache.solr.schema.TextField" name="TextField">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
<fieldType class="org.apache.solr.schema.TrieIntField" name="TrieIntField"/>
</types>
<fields>
<field indexed="true" multiValued="false" name="nombrecompleto" stored="true" type="TextField"/>
<field indexed="true" multiValued="false" name="apellido" stored="true" type="TextField"/>
<field indexed="true" multiValued="false" name="nombre" stored="true" type="TextField"/>
<field docValues="true" indexed="true" multiValued="false" name="id" stored="true" type="TrieIntField"/>
<field indexed="true" multiValued="false" name="all" stored="false" type="TextField"/>
<field indexed="true" multiValued="true" name="uimaname" stored="true" type="TextField"/>
</fields>
<uniqueKey>id</uniqueKey>
<defaultSearchField>all</defaultSearchField>
<copyField source="nombrecompleto" dest="all"/>
<copyField source="apellido" dest="all"/>
<copyField source="nombre" dest="all"/>
</schema>
solr_config如下:

当我使用CQL插入数据时,数据已在Lucene中正确编制索引,搜索工作正常,但是uima注释器无法正常工作。此外,当我上传文件到solr trought Sol命令时,文档成功编制索引,搜索也可以在CQL中工作,但uima既不起作用。我检查了日志,但没有显示任何错误。
我在Solr Apache发行版(v6.0.1)中做了相同的过程,它按预期工作。
我没有看到DSE_HOME中的核心文件编辑文件是为了方便,我还没有在DSE搜索中成功实现UIMA集成,我在DSE搜索的核心配置中缺少什么?
答案 0 :(得分:1)
通过不遵循Solr文档程序找到答案,而是使用DSE文档,特别是Update request processor and field transformer (FIT) [2017-07-17]。
可以在DSE here [2017-07-17]
中找到一个示例上面链接的过程显示了索引时如何映射字段。通过创建一个适合UITA项目的jar到FIT项目并将类添加到solrconfig.xml
此过程允许使用Solr命令和带有solr_query的cql对添加的元数据进行搜索。
