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.

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...

data.table making a copy of table in R -

i doing this: myfun <- function(inputvar_vec){ # inputvar_vec input vector # # result = output vector return(result) } dt[, result := lapply(.sd, myfun), = byvar, .sdcols = inputvar] i getting following warning: warning message: `in `[.data.table`(df1, , `:=`(prop, lapply(.sd, propeventinlastk)), : invalid .internal.selfref detected , fixed taking copy of whole table, := can add new column reference. @ earlier point, data.table has been copied r (or been created manually using structure() or similar). (and more stuff) .... ` my guess because stacking result vectors (after operation), copy being made? can suggest method remove warning? have done using apply functions , thought should extendable here too. my other question is: can pass chunk of rows data frame (subsetted using statement), , call function myfun operate on that? adding example requested # generate data n = 10000 default=na value = 1 df = data.table(id = sample(1:5000, n, replace=true), ...
