Solr query for same keyword returning different results? -

-

I am using the text_general type to search in the Solr index with the configuration below. 

  & lt; FieldType name = "text_general" class = "solr.TextField" statusIncantgap = "100" & gt; & Lt; Analyzer Type = "Index" & gt; & Lt; Tokenizer class = "solr.StandardTokenizerFactory" /> & Lt; Filter class = "solr.SnowballPorterFilterFactory" /> & Lt; Filter class = "org.apache.solr.analysis.WordDelimiterFilterFactory" generWordParts = "1" generNumberParts = "1" catenateWords = "1" catenateNumbers = "1" catenateAll = "1" splitOnCaseChange = "1" splitOnNumerics = "1" protected Basic = "1" stem EnglishPositive = "1" /> & Lt; Ignore filter class = "solr.StopFilterFactory" = "true" word = "stopwords.txt" /> & Lt; -! In this example, we will only use synonyms from query time at & lt; Filter class = "solr.SynonymFilterFactory" Synonyms = "index_synonyms.txt" ignoreCase = "true" expansion = "false" /> - & gt; & Lt; Filter class = "solr.LowerCaseFilterFactory" /> & Lt; / Analyzer & gt; & Lt; Analyzer type = "query" & gt; & Lt; Tokenizer class = "solr.StandardTokenizerFactory" /> & Lt; Filter class = "solr.SnowballPorterFilterFactory" /> & Lt; Ignore filter class = "solr.StopFilterFactory" = "true" word = "stopwords.txt" /> & Lt; Ignore filter class = "solr.SynonymFilterFactory" synonyms = "synonyms.txt" = "true" detailed = "true" /> & lt; Filter class = "solr.LowerCaseFilterFactory" /> & Lt; / Analyzer & gt; & Lt; / FieldType & gt;

I have indexed a lot of content and searched with keywords: Please, please and please.

Please give the keyword query a very small result.

q =% 22PLEASE% 22 & amp; Q.op = or & amp; DF = Text & amp; Qt =% 2Fselect & amp; Type = CONTENT_NAME + desc & amp; Fq = content_source% 3asharepoint & amp; AuthenticatedUserName = Fine

but please & amp; Please give large resultset

q =% 22please% 22 &. Q.op = or & amp; DF = Text & amp; Qt =% 2Fselect & amp; Type = CONTENT_NAME + desc & amp; Fq = content_source% 3asharepoint & amp; AuthenticatedUserName = Fine

q =% 22Please% 22 & amp; Q.op = or & amp; DF = Text & amp; Qt =% 2Fselect & amp; Type = CONTENT_NAME + desc & amp; Fq = content_source% 3asharepoint & amp; AuthenticatedUserName = Fine

Even when I am using WordDelimiterFilterFactory, please consider it, please & amp; Please as a single keyword?

Any ideas.

You have a fundamental conflict using your tokenizer and filter SnowBallPorterFilterFactory to work correctly. Input Required:

Public Ultimate Class PorterStemFilter TokenFilter

According to the porter-generated algorithm, the changed token section is expanded. Note: In order to filter the generated, the input must already be in lower case, so that you will need to work in order to use the LowerCaseFilter or LowerCaseTokenizer further in order to work properly under the Tokenizer series

< / Blockquote>

This will motivate you to run your LowerSafefilterhere before running the stream in SnowBallPorterFilterFactory.

You are also using WordDelimiterFilterFactory after generating -. Which means that new words will not be precipitated after running through WordDelimiterFilterFactory.

Fixing is not as simple as putting it in frontCarCaseFilterFactory, because when the Snowball PorterFilterFactory will fix the issue, then He will interfere with the Word Delimiter Filter Factory, in which case will create new words on the change.

I suggest trying the following order:

StandardTokenizerFactory

WordDelimiterFilterFactory

LowerCaseFilterFactory

SynonymFilterFactory

StopFilterFactory

SnowballPorterFilterFactory

When you start to use as many filters as this is difficult to get a correct sequence as this but I believe That it will solve your current issues. As always, I suggest running multiple tests with my usual words from my document set to see how well it matches your desired output.

How to access user directory in lazarus? -

After I am trying to open file changelog.txt and it does not matter if I open it Need to have the user open it though it is always located in the ~ / directory. Enter the file here. Here is my code: Process TForm1.FormCreate (From: TObject); Var myFile: textfile; Line: String; Start AssignFile (myFile, '~ / changelog.txt'); Reset (myFile); While EOF (MyFile) does not readLn (myFile, Line); Label3.Caption: = (Label3.Capttion + Line + # 13 # 10); End; CloseFile (myFile); End; This does not work, however, if I replace ~ with the actual user name, then it works, however, I use the username of each user Can not know which will run my program. Any idea how can I get the username that started the program? ! Thanks Edit1: I have tried this, but this also includes a new line: RunCommand ('/ bin / bash', ['- - C ',' Whoami '], users); This is normal. The concept of "~" is an shell level and thus requires a separate shell elev...

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
