我正在尝试在Liferay 6.2中实现基于Lucene的索引和搜索。我有一个自定义服务生成器实体，并且希望能够搜索该实体的所有字段。但是问题在于，除非我在搜索框中明确键入field:value，否则它不会在所有索引字段中进行搜索。似乎只是在搜索liferay默认值，即
Field.ASSET_CATEGORY_TITLES, Field.ASSET_TAG_NAMES, Field.COMMENTS,
Field.CONTENT, Field.DESCRIPTION, Field.PROPERTIES, Field.TITLE,
Field.URL, Field.USER_NAME
这是我的实体
<entity name="Sample" local-service="true" remote-service="true" table="sample">
<column name="uuid_" type="String" />
<column name="sampleDbId" type="long" primary="true" />
<column name="sampleCollectionDbId" type="long" />
<column name="biobankDbId" type="long" />
<column name="hashedSampleId" type="String" />
<column name="hashedIndividualId" type="String" />
<column name="materialType" type="String" />
<column name="container" type="String" />
<column name="storageTemperature" type="String" />
<column name="sampledTime" type="Date"/>
<column name="anatomicalPartOntology" type="String" />
<column name="anatomicalPartOntologyVersion" type="String" />
<column name="anatomicalPartOntologyCode" type="String" />
<column name="anatomicalPartOntologyDescription" type="String" />
<column name="anatomicalPartFreeText" type="String" />
<column name="sex" type="String" />
<column name="ageLow" type="long" />
<column name="ageHigh" type="long" />
<column name="ageUnit" type="String" />
<column name="diseaseOntology" type="String" />
<column name="diseaseOntologyVersion" type="String" />
<column name="diseaseOntologyCode" type="String" />
<column name="diseaseOntologyDescription" type="String" />
<column name="diseaseFreeText" type="String" />
<column name="countryOfOrigin" type="String" />
<finder name="uuid" return-type="Collection">
<finder-column name="uuid_" />
</finder>
</entity>
我已经成功索引了所有要搜索的字段，并且可以在Luke中看到它。
我在索引器中对其进行索引，如下所示：
@Override
protected Document doGetDocument(Object obj) throws Exception {
// TODO Auto-generated method stub
System.out.println("-----doGetDocument called------");
Sample sample = (Sample)obj;
Document document = getBaseModelDocument(PORTLET_ID, sample);
if(sample.getSampleCollectionDbId() > 0){
document.addText("sampleCollectionName", SampleCollectionLocalServiceUtil.getSampleCollection(sample.getSampleCollectionDbId()).getName());
}
document.add(new Field("biobankName", BiobankGeneralInformationLocalServiceUtil.getBiobankGeneralInformation(sample.getBiobankDbId()).getBiobankName()));
document.add(new Field("materialType", sample.getMaterialType()));
//document.addText("biobankName", BiobankGeneralInformationLocalServiceUtil.getBiobankGeneralInformation(sample.getBiobankDbId()).getBiobankName());
//document.addKeyword("materialType", sample.getMaterialType());
document.addKeyword("container", sample.getContainer());
document.addText("storageTemperature", sample.getStorageTemperature());
document.addDate("sampledTime", sample.getSampledTime());
document.addText("anatomicalPartOntology", sample.getAnatomicalPartOntology());
document.addKeyword("anatomicalPartOntologyVersion", sample.getAnatomicalPartOntologyVersion());
document.addKeyword("anatomicalPartOntologyCode", sample.getAnatomicalPartOntologyCode());
document.addText("anatomicalPartOntologyDescription", sample.getAnatomicalPartOntologyDescription());
document.addText("anatomicalPartFreeText", sample.getAnatomicalPartFreeText());
document.addKeyword("sex", sample.getSex());
document.addNumber("ageLow", sample.getAgeLow());
document.addNumber("ageHigh", sample.getAgeHigh());
document.addText("ageUnit", sample.getAgeUnit());
document.addText("diseaseOntology", sample.getDiseaseOntology());
document.addKeyword("diseaseOntologyVersion", sample.getDiseaseOntologyVersion());
document.addKeyword("diseaseOntologyCode", sample.getDiseaseOntologyCode());
document.addText("diseaseOntologyDescription", sample.getDiseaseOntologyDescription());
document.addText("diseaseFreeText", sample.getDiseaseFreeText());
document.addKeyword("countryOfOrigin", sample.getCountryOfOrigin());
return document;
}
我还在localserviceimpl类中定义了Hits搜索方法：
public Hits search(long companyId, String keywords) throws SearchException{
System.out.println("-----SampleLocalServiceImpl search called------");
SearchContext searchContext = new SearchContext();
searchContext.setAndSearch(false);
Map<String, Serializable> attributes = new HashMap<String, Serializable>();
attributes.put("sampleCollectionName", keywords);
attributes.put("biobankName", keywords);
attributes.put("materialType", keywords);
attributes.put("container", keywords);
attributes.put("storageTemperature", keywords);
attributes.put("sampledTime", keywords);
attributes.put("anatomicalPartOntology", keywords);
attributes.put("anatomicalPartOntologyVersion", keywords);
attributes.put("anatomicalPartOntologyCode", keywords);
attributes.put("anatomicalPartOntologyDescription", keywords);
attributes.put("anatomicalPartFreeText", keywords);
attributes.put("sex", keywords);
attributes.put("ageLow", keywords);
attributes.put("ageHigh", keywords);
attributes.put("ageUnit", keywords);
attributes.put("diseaseOntology", keywords);
attributes.put("diseaseOntologyVersion", keywords);
attributes.put("diseaseOntologyCode", keywords);
attributes.put("diseaseOntologyDescription", keywords);
attributes.put("diseaseFreeText", keywords);
attributes.put("countryOfOrigin", keywords);
searchContext.setAttributes(attributes);
searchContext.setCompanyId(companyId);
searchContext.setKeywords(keywords);
System.out.println(searchContext.getAttributes());
QueryConfig queryConfig = new QueryConfig();
queryConfig.setHighlightEnabled(false);
queryConfig.setScoreEnabled(false);
//searchContext.setAttribute("materialType:", keywords);
searchContext.setQueryConfig(queryConfig);
System.out.println(searchContext.getCompanyId());
Indexer indexer = IndexerRegistryUtil.nullSafeGetIndexer(
Sample.class);
System.out.println("-----SampleLocalServiceImpl search called------"+indexer.getFullQuery(searchContext));
System.out.println("-----SampleLocalServiceImpl search called------"+indexer);
return indexer.search(searchContext);
}
我正在通过本地服务实用程序类从我的jsp调用此搜索方法。
因此，当我在搜索框中键入
blood时，没有任何结果，但是当我键入materialType:blood时，却得到了结果。对于空搜索，查询日志给了我
+(+((+(entryClassName:com.xxx.portlet.xxx.model.Sample))))（给出完整的结果集）如果输入血，查询日志会给我
+(+((+(entryClassName:com.xxx.portlet.xxx.model.Sample)))) +(assetCategoryTitles:*blood* assetTagNames:*blood* comments:blood content:blood description:blood properties:blood title:blood url:blood userName:*blood*)（空结果集）
如果我输入materialType：blood，查询日志会给我
+(+((+(entryClassName:com.xxx.portlet.xxx.model.Sample))))+(materialType:*blood* materialType:blood)（匹配结果集）我想要的是用户能够只在框中键入自由文本并获取匹配的结果。但是目前这还行不通，因为自由文本搜索只是在liferay默认字段上搜索。我怎样才能解决这个问题？
该问题也发布在here上。
最佳答案
在searchContext.setAttributes(attributes);类的Hits search method中设置localserviceimpl是不够的。我还必须重写postProcessSearchQuery类中的indexer方法。因此，在我的indexer类中添加了以下方法后，我开始使用它。
@Override
public void postProcessSearchQuery(BooleanQuery searchQuery, SearchContext searchContext)
throws Exception {
System.out.println("-----postProcessSearchQuery called------");
addSearchTerm(searchQuery, searchContext, "sampleCollectionName", true);
addSearchTerm(searchQuery, searchContext, "biobankName", true);
addSearchTerm(searchQuery, searchContext, "materialType", true);
addSearchTerm(searchQuery, searchContext, "container", true);
addSearchTerm(searchQuery, searchContext, "storageTemperature", true);
.....
.....
LinkedHashMap<String, Object> params =
(LinkedHashMap<String, Object>)searchContext.getAttribute("params");
if (params != null) {
String expandoAttributes = (String)params.get("expandoAttributes");
if (Validator.isNotNull(expandoAttributes)) {
addSearchExpando(searchQuery, searchContext, expandoAttributes);
}
}
}
