Can you do sorting and grouping for the search results in solr using the solr config files? -

-

assume indexed fields includes: product name product type product release date

assume solr request handler type dismax.

is possible sort , group search results in solr search engine using solr config files, schema.xml , solrconfig.xml?

for example, when search spider man, if search results came products of spider man dvds , spider man comic books, , mixed 1 after this: spiderman1, dvd spiderman1, book spiderman2, book spiderman3, dvd spiderman4, book

is possible group results, dvds next each other , books next each other using solr config files? if yes, can give example of how it?

also possible sort result putting recent released dvds , books show on top of result using solr sonfig files? if yes, can give example of how it?

solr supports grouping (also called field collapsing) allow group results per product type.
configuration can added default request handler defination in solrconfig.xml applied always.

<requesthandler name="/browse" class="solr.searchhandler">  <lst name="defaults">    <!-- query settings -->    <str name="deftype">edismax</str>    <str name="qf">       text^0.5 features^1.0 name^1.2 sku^1.5 id^10.0 manu^1.1 cat^1.4       title^10.0 description^5.0 keywords^5.0 author^2.0 resourcename^1.0    </str>    <str name="df">text</str>    <str name="mm">100%</str>    <str name="q.alt">*:*</str>    <str name="rows">10</str>    <str name="fl">*,score</str>     <!-- faceting defaults -->    <str name="group">true</str>    <str name="group.field">product_type</str>     ...................   </lst> </requesthandler>

the group configuration defined defaults , can overridden passing parameters.

there 2 sort parameters available allow sort results groups , within groups.

sort -

how sort groups relative each other. example, sort=popularity desc cause groups sorted according highest popularity doc in each group. defaults "score desc".

note highest popularity, sort depend on max or latest result single document entire group.

group.sort -

how sort documents within single group. defaults same value sort parameter.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
