Schema.xml, copyField, Slash, ignoreCase ?

[Bruno Mannina]

Hello,



I’m facing a problem concerning the default field “text” (SOLR 5.4) and
queries which contains / (slash)



I need to have default “text” field with:

- ignoreCase,

- no auto truncation,

- process slash char



I would like to perform only query on the field “text”

Queries can contain:  code or keywords or both.



I have 2 fields named symbol and title, and 1 alias ti (old field that I
can’t delete or modify)



* Symbol contains code with slash (i.e A62C21/02)

<field name="symbol" type="string_ci" multiValued="false" indexed="true"
required="true" stored="true"/>



* Title contains English text and also symbol

    <field name="title" type="text_en" multiValued="true" indexed="true"
stored="true" termVectors="true" termPositions="true" termOffsets="true"/>



{ "symbol": "B65D81/20",

"title": [

 "under vacuum or superatmospheric pressure, or in a special atmosphere,
e.g. of inert gas  {(B65D81/28  takes precedence; containers with
pressurising means for maintaining ball pressure A63B39/025)} "

]}



* Ti is an alias of title

    <field name="ti" type="text_general" multiValued="true" indexed="true"
stored="true" termVectors="true" termPositions="true" termOffsets="true"/>



* Text is

<field name="text" type="text_general" indexed="true" stored="false"
multiValued="true"/>



- Alias are:



    <copyField source="title"  dest="ti"/>

    <!-- ALIAS TEXT -->

    <copyField source="title"  dest="text"/>

    <copyField source="symbol" dest="text"/>





If I do these queries :



* ti:airbag                           à it’s ok

* title:airbag                      à not good for me because it found
airbags

* ti:b65D81/28                  à not good, debug shows ti:b65d81 OR ti:28

* ti:”b65D81/28”              à it’s ok

* symbol:b65D81/28      à it’s ok (even without “ “)



NOW with “text” field

* b65D81/28                      à not good, debug shows text:b65d81 OR
text:28

* airbag                               à it’s ok

* “b65D81/28”                  à it’s ok



It will be great if I can enter symbol without “ “



Could you help me to have a text field which solve this problem ? (please
find below all def of my fields)



Many thanks for your help.
