exact-match

I'm using elasticsearch and am having a devil of a time getting an exact match to happen. I've tried various combinations of match, query_string, etc, and I either get nothing or bad results. Query looks like this: { "filter": { "term": { "term": "dog", "type": "main" } }, "query": { "match_phrase": { "term": "Dog" } }, "sort": [ "_score" ] } Sorted results 10.102211 {u'term': u'The Dog', u'type': u'main', u'conceptid': 7730506} 10.102211 {u'term': u'That Dog', u'type': u'main', u'conceptid': 4345664} 10.102211 {u'term': u'Dog', u'type': u'main', u'conceptid': 144} 7.147442 {u'term': u'Dog Eat

I could not find a better title, I hope to change it later if possible upon your eventual sugestions. My problem: I got a database with music artists. These look like this: "dr. dre feat. akon", "eminem & dr. dre", "dr. dre feat. ll cool j", "dr. dre", "dr. dre feat. eminem & skylar grey". We only have two fields: id and name.

Note that they got the exact same score. What I want is to have "dr. dre" as a

I am looking for a way to check if an exact string match exists in another string using Regex or any better method suggested. I understand that you tell regex to match a space or any other non-word character at the beginning or end of a string. However, I don't know exactly how to set it up. Search String: t String 1: Hello World, Nice to see you! t String 2: Hello World, Nice to see you! String 3: T Hello World, Nice to see you! I would like to use the search string and compare it to String 1, String 2 and String 3 and only get a positive match from String 1 and String 3 but not from String 2

I've got a big text file. I need to extract all the lines which contains the exact word "DUSP1". Here an example of the lines: 9606 ENSP00000239223 DUSP1 BLAST 9606 ENSP00000239223 DUSP1-001 Ensembl I want to retrieve the first line but not the second one. I tried several commands as: grep -E "^DUSP1" grep '\<DUSP1\>' grep '^DUSP1$' grep -w DUSP1 But none of them seem to work. Which option should I use? The problem you are facing is that a dash (-) is considered by grep as a word delimiter. You should try this command : grep '\sDUSP1\s' file to ensure that there's spaces around your word. If

\\ $DigitalSignature have full name value passed $SignatureMatch = '/' . strtolower( $NameFirst . ' ' . $NameLast ) . '$/'; if( true == preg_match( $SignatureMatch, strtolower( $DigitalSignature ) ) ) { $boolIsValid = true; } I am having this code for exact matching first name and last name match with digital signature. But this gives error reported me in error log on production(live). preg_match(): Unknown modifier 'b' I am unable to reproduce this error. How can I get this error firstly. And how to resolve this error for exact matching. I have seen many questions on SO but not getting when
