java - Add a custom field type in solr -


in solr schema.xml many field types defined. example

<fieldtype name="int" class="solr.trieintfield" precisionstep="0" positionincrementgap="0"/>

is definition integer field.

how define custom field types inside solr?

is possible add java types such biginteger, bigdecimal, map , other types field type in solr?

you can define new custom fields in solr adding them schema.xml in <fields> element:

<fields> ... <field name="newfieldname" type="text_general" indexed="true" stored="true" multivalued="true"/> ... </fields>

to have overview on supported types (used define <fieldtype> in solr, used define field elements), take link: https://cwiki.apache.org/confluence/display/solr/field+types+included+with+solr. example, type "text_general" defined in schema.xml as:

<fieldtype name="text_general" class="solr.textfield" positionincrementgap="100">   <analyzer type="index">     <tokenizer class="solr.standardtokenizerfactory"/>     <filter class="solr.stopfilterfactory" ignorecase="true" words="stopwords.txt" enablepositionincrements="true" />     <filter class="solr.lowercasefilterfactory"/>   </analyzer>   <analyzer type="query">     <tokenizer class="solr.standardtokenizerfactory"/>     <filter class="solr.stopfilterfactory" ignorecase="true" words="stopwords.txt" enablepositionincrements="true" />     <filter class="solr.synonymfilterfactory" synonyms="synonyms.txt" ignorecase="true" expand="true"/>     <filter class="solr.lowercasefilterfactory"/>   </analyzer> </fieldtype>

you can see uses class="solr.textfield" basic field type. solr schema has several types defined default... can define more, not sure if can defined ones asking for.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
