Re: Help on Notification for SOLR
of course there is another approach which is using Solr Clients. So, you can use solr clients for specific language like PHP, JAVA, ... For Example : JAVA Solr Client : SolrJ is an API that makes it easy for Java applications to talk to Solr. SolrJ hides a lot of the details of connecting to Solr and allows your application to interact with Solr with simple high-level methods. String urlString = http://localhost:8983/solr;; SolrServer solr = new HttpSolrServer(urlString); SolrInputDocument document = new SolrInputDocument(); document.addField(id, 552199); document.addField(name, Gouda cheese wheel); document.addField(price, 49.99); UpdateResponse response = solr.add(document); // Remember to commit your changes! solr.commit(); If you want another language, you can tell me and I will help you .

Re: Indexing nested document to support blockjoin queries in solr 4.10.1
You can model this in different ways, depending on your searching/faceting needs. Usually you'll use multivalued or dynamic fields. In the next examples I'll omit the field type, indexed and stored flags: field name=name type=text indexed=true stored=true / field name=c_name type=string indexed=true stored=true multiValued=true/ field name=c_age type=int indexed=true stored=true multiValued=true / field name=c_sex type=string indexed=true stored=true multiValued=true/ Another one: dynamicField name=c_name_* type=string indexed=true stored=true/ dynamicField name=c_age_* type=string indexed=true stored=true/ dynamicField name=c_sex_* type=string indexed=true stored=true/ Here you would store fields 'c_name_1', 'c_age_1', 'c_name_2', 'c_age_2', etc. Again it's up to you to correlate values, but at least you have an index. With some code you could make this transparent. Solr wiki says: Solr provides one table. Storing a set database tables in an index generally requires denormalizing some of the tables. Attempts to avoid denormalizing usually fail. It's up to you to denormalize your data according to your search needs.

Re: Automating Solr
Simple add this line to your crontab with crontab -e command:
0,30 * * * * /usr/bin/wget
http://solr_host:8983/solr/core_name/dataimport?command=full-import
This will full import every 30 minutes. Replace solr_host and core_name
with your configuration
*Using delta-import command*
Delta Import operation can be started by hitting the URL
http://localhost:8983/solr/dataimport?command=delta-import. This operation
will be started in a new thread and the status attribute in the response
should be shown busy now. Depending on the size of your data set, this
operation may take some time. At any time, you can hit
http://localhost:8983/solr/dataimport to see the status flag.
When delta-import command is executed, it reads the start time stored in
conf/dataimport.properties. It uses that timestamp to run delta queries and
after completion, updates the timestamp in conf/dataimport.properties.
Note: there is an alternative approach for updating documents in Solr, which
is in many cases more efficient and also requires less configuration
explained on DataImportHandlerDeltaQueryViaFullImport.
*Delta-Import Example*
We will use the same example database used in the full import example. Note
that the database schema has been updated and each table contains an
additional column last_modified of timestamp type. You may want to download
the database again since it has been updated recently. We use this timestamp
field to determine what rows in each table have changed since the last
indexed time.
Take a look at the following data-config.xml
dataConfig
dataSource driver=org.hsqldb.jdbcDriver
url=jdbc:hsqldb:/temp/example/ex user=sa /
document name=products
entity name=item pk=ID
query=select * from item
deltaImportQuery=select * from item where
ID='${dih.delta.id}'
deltaQuery=select id from item where last_modified gt;
'${dih.last_index_time}'
entity name=feature pk=ITEM_ID
query=select description as features from feature where
item_id='${item.ID}'
/entity
entity name=item_category pk=ITEM_ID, CATEGORY_ID
query=select CATEGORY_ID from item_category where
ITEM_ID='${item.ID}'
entity name=category pk=ID
query=select description as cat from category where
id = '${item_category.CATEGORY_ID}'
/entity
/entity
/entity
/document
/dataConfig
Pay attention to the deltaQuery attribute which has an SQL statement capable
of detecting changes in the item table. Note the variable
${dataimporter.last_index_time} The DataImportHandler exposes a variable
called last_index_time which is a timestamp value denoting the last time
full-import 'or' delta-import was run. You can use this variable anywhere in
the SQL you write in data-config.xml and it will be replaced by the value
during processing.

Re: Boosting on field-not-empty
You can use FunctionQuery that allows one to use the actual value of a field
and functions of those fields in a relevancy score.
Two function will help you, which are :
*exists*
exists(field|function) returns true if a value exists for a given document.
Example use: exists(myField) will return true if myField has a value, while
exists(query({!v='year:2012'})) will return true for docs with year=2012.
*if*
if(expression,trueValue,falseValue) emits trueValue if the expression is
true, else falseValue. An expression can be any function which outputs
boolean values, or even functions returning numeric values, in which case
value 0 will be interpreted as false, or strings, in which case empty string
is interpreted as false.
Example use: if(exists(myField),100,0) returns 100 if myField exists
*Solution: *
Use in a parameter that is explicitly for specifying functions, such as the
EDisMax query parser's boost param, or DisMax query parser's bf (boost
function) parameter. (Note that the bf parameter actually takes a list of
function queries separated by white space and each with an optional boost.
Make sure you eliminate any internal white space in single function queries
when using bf). For example:

Re: Nested documents in Solr

(title:foo bar AND body:quick fox) OR title:fox Search for word foo and not bar in the title field. title:foo -title:bar *Wildcard matching* Search for any word that starts with foo in the title field. title:foo* Search for any word that starts with foo and ends with bar in the title field. title:foo*bar Note that Lucene doesn't support using a * symbol as the first character of a search. -- View this message in context: http://lucene.472066.n3.nabble.com/Nested-documents-in-Solr-tp4165099p4165232.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: SolrJ and Lucene queries

Re: SolrJ and Lucene queries
Yeah, it's a shame such a ser/deser feature isn't available in Lucene. My idea is to have a separate module that the Query classes can delegate to for serialization and deserialization, handling recursion for nested query objects, and then have modules for XML, JSON, and a pseudo-Java functional notation (maybe closer to JavaScript) for the actual formatting and parser. And then developers can subclass the module to add any custom Query classes of their own. A full JSON query ser/deser would be an especially nice addition to Solr, allowing direct access to all Lucene Query features even if they haven't been integrated into the higher level query parsers. And maybe the format should have a flag for whether terms have been analyzed or not. Then, deserialization could optionally do analysis as well. The Solr QueryParsing.toString method shows a purely external approach to serialization (I've done something similar myself.) This is what is output in the parsedquery section of debugQuery output for a Solr query response. -- View this message in context: http://lucene.472066.n3.nabble.com/SolrJ-and-Lucene-queries-tp4165233p4165290.html Sent from the Solr - User mailing list archive at Nabble.com.

Re: Word Break Spell Checker Implementation algorithm
WordBreakSolrSpellChecker offers suggestions by combining adjacent query terms and/or breaking terms into multiple words. It is a SpellCheckComponent enhancement, leveraging Lucene's WordBreakSpellChecker. It can detect spelling errors resulting from misplaced whitespace without the use of shingle-based dictionaries and provides collation support for word-break errors, including cases where the user has a mix of single-word spelling errors and word-break errors in the same query. It also provides shard support. Here is how it might be configured in solrconfig.xml: http://lucene.472066.n3.nabble.com/file/n4164997/Screen_Shot_2014-10-20_at_9.png Some of the parameters will be familiar from the discussion of the other spell checkers, such as name, classname, and field.

The spellchecker can be configured with a traditional checker (ie: DirectSolrSpellChecker). The results are combined and collations can contain a mix of corrections from both spellcheckers.

The query also includes a spellcheck.build=true parameter, which is needs to be called only once in order to build the index. spellcheck.build should not be specified with for each request. http://localhost:8983/solr/spellCheckCompRH?q=*:*spellcheck.q=hell%20ultrasharspellcheck=truespellcheck.build=true lst name=spellcheck lst name=suggestions lst name=hell int name=numFound1/int int name=startOffset0/int int name=endOffset4/int arr name=suggestion strdell/str /arr /lst lst name=ultrashar int name=numFound1/int int name=startOffset5/int int name=endOffset14/int arr name=suggestion strultrasharp/str /arr /lst /lst /lst Once the suggestions are collected, they are ranked by the configured distance measure (Levenstein Distance by default) and then by aggregate frequency. -- View this message in context: http://lucene.472066.n3.nabble.com/How-to-properly-use-Levenstein-distance-with-in-Java-tp4164793p4164883.html Sent from the Solr - User mailing list archive at Nabble.com.

Hi, I would like to help me for certain problem. My problem is : I have documents and I do group by on certain field (e.g. Field1). I want to get documents with Field2 is [3 or 9 or 12] if exist, otherwise get any document. please see the below example. D1 :--- Field1 : 1 - Field2 : 3 - D1 (group by on field1 and field2 is 3) - D2: --- Field1 : 1 Field2 : 4 D3:--- Field1 : 2 - Field2 : 5-- any document D3 or D4 - D4:--- Field1 : 2 Field2 : 7 I want to get the results like below D1(Mandatory) (D3 OR D4) -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-Condition-Before-Group-By-tp4005179.html Sent from the Solr - User mailing list archive at Nabble.com.
Missing Features - AndMaybe and Otherwise
Hi, I would like to help me for certain problem. I have encountered a problem in task I think if you implement the below functions/conditions, you will help us for many issues. *AndMaybe(a, b)* Binary query takes results from the first query. If and only if the same document also appears in the results from the second query, the score from the second query will be added to the score from the first query. *Otherwise(a, b)* A binary query that only matches the second clause if the first clause doesn’t match any documents. My problem is : I have documents and I do group by on certain field (e.g. Field1). I want to get documents with Field2 is [3 or 9 or 12] if exist, otherwise get any document. please see the below example.

Solr Partial and Exact Matching
I want to ask you about partial and exact matching. I have documents for Places and we need to get exact match if the user search for place name and get the results based on other factors (not place name) if the query is general or partial. This is an example to explain more details. If we suppose that schema for our documents contains 2 fields like below. field name=Place Title type=text indexed=true stored=true required=true/ field name=Review type=text indexed=true stored=true multiValued=true/ and we have 2 documents D1 : Place Title : Pizza Hut Review : Nice meal D2 : Place Title : Little Caesar Review : Nice Pizza If the user search for general query like pizza only, we will decrease the rank for place title to support reviews like qf= place_title^1 review^2 But if we search about exact match like Pizza Hut, we will increase the rank qf= place_title^5 review^2 I have many idea like using term frequency and many approach but I need the best practice for implenting it.

Re: Solr Score threshold 'reasonably', independent of results returned
It will never return no result because its relative to score in previous result If score0.25*last_score then stop Since score0 and last score is 0 for initial hit it will not stop -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-Score-threshold-reasonably-independent-of-results-returned-tp4002312p4003247.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: Solr Score threshold 'reasonably', independent of results returned
You are right Mr.Ravish, because this depends on (ranking and search fields) formula, but please allow me to tell you that Solr score can help us to define this document is relevant or not in some cases. -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-Score-threshold-reasonably-independent-of-results-returned-tp4002312p4003248.html Sent from the Solr - User mailing list archive at Nabble.com.
Solr Score threshold 'reasonably', independent of results returned
Usually, search results are sorted by their score (how well the document matched the query), but it is common to need to support the sorting of supplied data too. Boosting affects the scores of matching documents in order to affect ranking in score-sorted search results. Providing a boost value, whether at the document or field level, is optional. When the results are returned with scores, we want to be able to only keep results that are above some score (i.e. results of a certain quality only). Is it possible to do this when the returned subset could be anything? I ask because it seems like on some queries a score of say 0.008 is resulting in a decent match, whereas other queries a higher score results in a poor match. I have written pseudo code to achieve what I said.

Facet count problem : Multi-Select Faceting After grouping results
Dear All ,
Kindly note that I using Solr 4.0 and Kindly note that
/*group.truncate=true*/ calculates facet counts that based on the most
relevant document of each group matching the query.
*But* when I used Multi-Select Faceting [Tagging and excluding Filters] ,
the solr can't calculate the facet after grouping the results and select
multi facet.
