solr的schema.xml配置文件在配置Filed的时候,有个属性:ui
MutiValued:true if this field may containmutiple values per documents,这个说明有点模糊,下面结合实际应用,列举两个不一样的例子。this
例子一:一个field有多个值,值来自同一filedspa
-
-
-
<field name="id" type="int" indexed="true" stored="true" multiValued="false" required="true"/>
-
<field name="planTime" type="tdate" indexed="true" stored="false" multiValued="false" />
-
<field name="state" type="string" indexed="true" stored="false" multiValued="false" />
-
<field name="overDate" type="string" indexed="true" stored="false" multiValued="false" />
-
<field name="type" type="int" indexed="true" stored="false" multiValued="false" />
-
<field name="contactName" type="textComplex" indexed="true" stored="false" multiValued="false" />
-
<field name="contactTel" type="string" indexed="true" stored="false" multiValued="false" />
-
<field name="customer" type="textComplex" indexed="true" stored="false" multiValued="false" />
-
<field name="alias" type="textComplex" indexed="true" stored="false" multiValued="false" />
-
<field name="englishName" type="textComplex" indexed="true" stored="false" multiValued="false" />
-
<field name="executor" type="int" indexed="true" stored="true" multiValued="true" />
-
-
<field name="keywords" type="text" indexed="true" stored="false" multiValued="true"/>
-
其中:code
-
<field name="executor" type="int" indexed="true" stored="true" multiValued="true" /
-
最后看下查询效果:xml

从上图看书,executor这个field能够多个值,任何executor:29 OR executor:40,相似查询都能查出id为3的记录。索引
附注:使用solrj建此索引时,定义成集合类型便可,如:ip
-
-
private Set<Integer> executor;
-
-
public Set<Integer> getExecutor() {
-
-
-
-
public void setExecutor(Set<Integer> executor) {
-
this.executor = executor;
-
例子二:相似综合搜索,结合copyFiled使用,多个Filed拷贝到该Field上get

从上图看出keywords区域,是name、introduction、industryName三个的集合,不管搜索name、introduction、industryName中任意一个,都能经过keywords搜索出来。string
