> Time Spent: 40m
> Remaining Estimate: 0h
>
> *Replication Steps*
> 1. Have two multi-value fields with the following schema
> {code:java}
> <field name="docTags" type="plongs" multiValued="true" indexed="true"
> stored="true"/><field name="tg0001" type="ipro_strings" multiValued="true"
> indexed="true" stored="true"/>
> <fieldType name="plong" class="solr.LongPointField" docValues="true"/>
> <fieldType name="ipro_strings" class="solr.TextField" sortMissingLast="true"
> multiValued="true">
> <analyzer>
> <tokenizer class="solr.KeywordTokenizerFactory"/>
> <filter class="solr.LowerCaseFilterFactory"/>
> </analyzer>
> </fieldType>
> {code}
> 2. Execute the following UpdateXmlMessage
> {code:java}
> <add commitWithin="1000">
> <doc>
> <field name="_id">1</field>
> <field name="docTags" update="remove"><![CDATA[1]]></field>
> <field name="tg0001" update="remove"><![CDATA[Convert to Image]]></field>
> <field name="docTags" update="remove"><![CDATA[4]]></field>
> <field name="tg0001" update="remove"><![CDATA[Large Files]]></field>
> <field name="docTags" update="remove"><![CDATA[6]]></field>
> <field name="tg0001" update="remove"><![CDATA[To Bulk-Print]]></field>
> </doc>
> </add>
> <add commitWithin="1000">
> <doc>
> <field name="_id">1</field>
> <field name="docTags" update="remove"><![CDATA[6]]></field>
> <field name="tg0001" update="remove"><![CDATA[To Bulk-Print]]></field>
> <field name="docTags" update="add-distinct"><![CDATA[1]]></field>
> <field name="tg0001" update="add-distinct"><![CDATA[Convert to
> Image]]></field>
> <field name="docTags" update="add-distinct"><![CDATA[4]]></field>
> <field name="tg0001" update="add-distinct"><![CDATA[Large Files]]></field>
> </doc>
> </add>
> <add commitWithin="1000">
> <doc>
> <field name="_id">1</field>
> <field name="docTags" update="remove"><![CDATA[1]]></field>
> <field name="tg0001" update="remove"><![CDATA[Convert to Image]]></field>
> <field name="docTags" update="remove"><![CDATA[4]]></field>
> <field name="tg0001" update="remove"><![CDATA[Large Files]]></field>
> <field name="docTags" update="add-distinct"><![CDATA[6]]></field>
> <field name="tg0001" update="add-distinct"><![CDATA[To Bulk-Print]]></field>
> </doc>
> </add> {code}
> 3. Observe the following defect of duplicate values in those fields for that
> document
> !image-2022-04-20-10-35-05-247.png!
> *Note:* If you add the data first in the Xml message and the update="remove"
> tags at the bottom, it works as expected and only adds once instance of the
> data from the above update="add-distinct" message. The issue only occurs if
> the remove tags come before the add-distinct tags.
>
> Is this because of some undocumented order the updates need to be in or is it
> a true defect that it is not working as expected?
