我有名称和尺寸的字段。字段为:Name
,dimensionLength
,dimensionWidth
和dimensionHeight
。
我希望查询productX 10x20
仅返回包含这两个维度的匹配项。因此,上面的查询可以返回productX 10x20x30
和productX 10x30x20
,但不应该返回productX 10x30x40
。
第一个结果很好,但我得到了许多其他不相关的匹配。任何想法如何避免这些不相关的结果?
澄清一下,字段是:
<field indexed="true" multiValued="true" name="Height_mm_Copy" stored="false" type="dimension"/>
<field indexed="true" multiValued="true" name="Outside_diameter_mm_Copy" stored="false" type="dimension"/>
<field indexed="true" multiValued="true" name="Inside_diameter_mm_Copy" stored="false" type="dimension"/>
<field indexed="true" name="name" stored="true" type="title"/>
尺寸的字段类型:
<fieldType class="solr.TextField" name="dimension" omitNorms="true" positionIncrementGap="100">

答案 0 :(得分:0)
通过制作&#34; name&#34;的副本字段来解决它。通过使用
此字段的fieldType中为<filter class="solr.PatternCaptureGroupFilterFactory" pattern="(\d+/*[xX]\d+)" preserve_original="false"/>
。所以来自string&#34;产品10x20x30&#34;只有&#34; 10x20&#34;仍然在此字段中编入索引。
