Re: generation of SOLR XML
hai, Yes the Xml formats is understood but there is an to generate these xmls from a data source. These XML feild tags doesnot contain the smae start tags and end tags. like field name=catsoftware/field and standerd xml writers have xml generated as the same start and end tags. in SOLR xml start tag = field name=cat end tag = /field can you adivise anything on this please. regards, aditya On 3/7/07, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: ...can any one guide me on this XML generation, which SOLR will accepts for indexing...

As previously discussed in email, there are two completley different appraoches that could be taken to achieve spell correction using Solr: 1) Use something like the Lucene SpellChecker contrib to make suggestions basedon the data in the main solr index (defined by the solr schema) ... adding hooks to Solr to keep the SpellChecker system aware of changes to the main index, and hooks to allow requesthandlers to return suggestions with each query 2) use the main solr index (defined by the schema) to store the dictionary of words, turning the entire solr instance into one giant SpellChecker. In this case there would be a recomended schema.xml for users who want to setup a SpellChecker Solr instance and possible a custom RequestHandler htat assumes you are using this schema. These two patches both seem to be dealing with case#1, but they have hints of approach#2 ... for example i don't entirely understand why they include the NGram tokenfilter factories, since they don't seem to need the fields of the solr index to be tokenized in any special way (since the lucene SpellChecker controls the format of it's dictionary). It's also not clear do me what the purpose of the SpellCheckerRequestHandler is ... if the main index is storing real user records, then wouldn't a helper method that existing request handlers (like dismax and standard) can optionally call to get the SpellChecker data be more useful?

[jira] Commented: (SOLR-183) add getRequiredParameter() to SolrParams
[ https://issues.apache.org/jira/browse/SOLR-183?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12478895 ] J.J. Larrea commented on SOLR-183: -- Er, sorry to be contrary, but to me it seems a bit excessive to go through so many hoops to support the getXXX(param, default) methods, which contradicts the very nature of the class, which is to require parameters. If one wanted to stick with Hoss' preference for a decorator, and kept the getXXX(param, default) method signatures defined in SolrParams, one could argue that it would make sense to make those methods simply return SolrExceptions, on the assumption that requires.getInt(param, 0) must be a programmer error. That is of course automatically achieved if only get and getParams are overridden, as was proposed earlier. It's not so terrible to maintain parallel params and requires references to the same underlying param list. But if one is going to bother adding real implementations for every method signature in SolrParams, then why not simply dispense with the decorator and add getRequiredXXX(param) methods with default implementations directly to SolrParams, e.g. getRequiredParam(String param) getRequiredParams(String param) getRequiredBool(String param) getRequiredFieldBool(String field, String param) ... etc. That seems simpler, straightforward, and unambiguous. add getRequiredParameter() to SolrParams Key: SOLR-183 URL: https://issues.apache.org/jira/browse/SOLR-183 Project: Solr Issue Type: Wish Reporter: Ryan McKinley Priority: Trivial Attachments: SOLR-183-required-param.patch, SOLR-183-required-param.patch I find myself including this with every patch, so i'll just separate it out.

Larrea commented on SOLR-183: -- Modest proposal: If one is going to come up with a programmer-facing mechanism for required parameters (using any of the abovementioned schemes), why not also make it configuration-facing as well. That is, in solrparams.xml: requestHandler name=blah class=solr.DisMaxRequestHandler lst name=defaults str name=version2.1/str int name=rows0/int ... /lst lst name=requires str name=qA query must be specified using the q parameter/str str name=versionThis handler depends on version being explicitly set/str /lst ... /requestHandler RequestHandlerBase would add to the definition and initialization of defaults, extends, and invariants, a fourth SolrParams called requires. Then when the init is building the (invariants -- ((request -- defaults) + appends))) chain with DefaultSolrParams and AppendedSolrParams (delegated to method SolrPluginUtils.setDefaults), it could interpose a new class RequiredSolrParams which acts like DefaultSolrParams except it accepts the 'requires' SolrParams defined in the handler config, which in my proposal defines a param name/message pair. If a param not found in the target SolrParams is defined in 'requires', the exception is thrown. Otherwise the RequiredSolrParams behaves similarly to DefaultSolrParams (which it extends) by delegating the request up the chain, or if no chain is defined returning null. Depending on what the programmer wants, the RequiredSolrParams could be chained with just the request params: (invariants - ((requires - request) - defaults) + appends) or could be chained with the entire chain as it exists: requires -- (invariants -- ((request -- defaults) + appends))) I've attached an illustrative implementation. I must apologize, while it compiles I have not yet tested it, I am under deadline and have spent too much time on this today already; I'll try to do so over the weekend, along with the RequestHandlerBase/SolrPluginUtils implementation. It accepts a requires SolrParams as described above, with the values interpreted as a Formatter string. It also has an always required mode with a method signature which accepts a fixed message format string. It also has a convenience method (temporarily commented out because of method signature clash) which shows how you can provide custom messages for some parameters but have a stock default message for others. I believe this object should be compatible with what Ryan posted, e.g. you could add implementations for getXXX(param, default) which override the throw the exception behavior it now has.

Larrea commented on SOLR-183: -- I was unfortunately not very clear, and confounded 2 things, an enhanced programmer-facing API, based on yours, for request-handler developers, and secondly an API supported by RequestHandlerBase for request handler configurators. From the programmer perspective, my contribution is simply to allow specification of either a global error format, and/or a parameter-specific definition of which parameters are required and how missing required parameters should be reported. It has no negative impact on the use case you desire, and the modified code should pass all the exists/doesn't exist tests in your RequiredSolrParamTest.java; if you slapped in your method signatures that return 400 SolrExceptions on bad type conversion, either into my RequiredSolrParams or SolrParams as I suggested above, it should pass all the tests, and if not, I will make it so. For example, MapString,String rmap = new HashMapString, String(); rmap.put( q , A query must be specified using the q parameter ); rmap.put( version , This handler depends on version being explicitly set ); SolrParams required = new RequiredSolrParams( params, new MapSolrParams( rmap ) ); This is similar to the suggestion in Hoss' first comment on this issue. The other use-case is for the RequestHandler configurator. There are a lot more of those than RequestHandler programmers. My model is that they are defining request handling service APIs by defining requestHandlers in solrconfig. Those APIs can be used by other web programmers in the organization, who will make mistakes in calling the API, as we all do. RequestHandlerBase gives RequestHandler configurators three options for controlling the API, the invariants defaults and appends. I am simply proposing a 4th option to define which parameters are required, and the error message that should be returned in the case it is missing. It's not a comprehensive parameter validation mechanism, but such would be beyond the scope of SOLR. However as someone who is actively creating RequestHandler APIs for other programmers in my organization, using custom code when necessary but avoiding it whenever possible, I think it might be useful. And in no way does this second use-case by itself allow RH configurators to override the first use-case requirements set up by RH programmers, unless the RH programmers make explicit provision to do so. For example, by chaining a DefaultSolrParams with params derived from a requestHandler requires list in front of a default MapSolrParams like the above, the RH programmer allows the RH configurator to add new requirements, and externally change the error strings for programmer-supplied requirements, but not to remove programmer-supplied requirements.
