Is it possible to get Solr's DataImportHadler to ignore fields with empty strings?

由 China☆狼群 提交于 2019-12-24 05:08:26
问题 I am using Solr's DataImportHandler to import data from a database. Some of the records have empty strings if there is no value for that column. Currently the configuration I have produces Solr documents like this: { "x": "value", "y": "", "z": 2 } However I would like to ignore all fields that have no value so that documents like this are created: { "x": "value", "z": 2 } Is there something I can define in the configuration file for the DataImportHandler that will give me my desired results?

Searching within a subset of data - Solr

由 有些话、适合烂在心里 提交于 2019-12-24 03:18:14
问题 I am new to Solr (Lucene) world. What I am trying to figure out is how would I search within a subset of data? Let me elaborate: I have 10 employees in my Employee table in the database. Each employee has n number of customers that are stored in the Customers table in the same database. When an employee is searching, I want to search only within that employee's customers. This is not exactly faceted search but I am pretty sure there is a way to do it in Solr looking at all the bells and

ToTitleCase in solr to stop SCREAMING CAPS in Solr

由 孤街醉人 提交于 2019-12-24 03:00:52
问题 I'm using solr's faceting and i've run into a problem that i was hoping i could get around using filters. Basically some times a town name will come through to SOLR as "CAMBRIDGE" and sometime's it will come through as "Cambridge" I wanted to use a filter in Solr to stop the SCREAMING CAPS version of the town name. It seems there is a fitler to make all the text lower case. <!-- A text field that only sorts out casing for faceting --> <fieldType name="text_facet" class="solr.TextField"

一、字段配置（schema） schema.xml位于solr/conf/目录下，类似于数据表配置文件， 定义了加入索引的数据的数据类型，主要包括type、fields和其他的一些缺省设置。 1、先来看下type节点，这里面定义FieldType子节点，包括name,class,positionIncrementGap等一些参数。 name：就是这个FieldType的名称。 class：指向org.apache.solr.analysis包里面对应的class名称，用来定义这个类型的行为。 view plaincopy to clipboardprint?
