Search List FirstOrDefault StartsWith fuzzy
c#,list,fuzzy-search,startswith
Here is a little trick you can use to do so : Artist Item = myList.Where(s => !String.IsNullOrEmpty(s)) .OrderBy(x => Math.Abs(x[0] - (int)'X')).FirstOrDefault(); Convert 'X' and first character of x to integer, order by the absolute value of the difference....
Neo4j schema indexes for fuzzy search
neo4j,cypher,spring-data-neo4j,fuzzy-search
Fuzzy search is a tricky thing. Even in plain lucene (where you can do fuzzy search with lucene query strings) it is not recommended because it is quite expensive. You can use that query syntax in Neo4j too when you indexed your data with a manual index. The solution that...
How to search for multiple strings in very large database
oracle,lucene,bigdata,fuzzy-search,string-search
The easiest way is: 1.) adding an index to the columns you like to search trough 2.) using oracle text as @lalitKumarB wrote The most powerful way is: 3.) use an separate search engine (solr, elaticsearch). But, probably you have to change you application in order to explicit use the...

A lot of time it is easier to prep your data ahead of time. To make your code simpler later. Here is what I would do create a reverse hash of non-punctuation names to the id. When looping the file I just have to have to compare against my non-punctuation...

Fuzzy matching movie titles without using a loop and extracting equivalent titles by release date
r,matching,string-matching,levenshtein-distance,fuzzy-search
You can merge these data frames z <- merge(df1,df2,by='release_date',suffixes=c('.df1','.df2')) which will give you a cartesian product (i.e. all possible combinations between df1 and df2 for the same release_date, and then calculate the Levenshtein distance by: z$L.dist <- lenvenshteinSim(z$title.df1,z$title.df2) Having z$L.dist, you can filter the desired rows: subset(z,L.dist > 0.85) Update...
Autocomplete and Fuzzy search across multiple indecies in Elasticsearch
search,elasticsearch,autocomplete,fuzzy-search
Use either GET /_all/_search endpoint or create an alias that gathers under it all the indices you want and use GET /[alias_name]/_search. As to which field to search, I think _all field could be a good match, depending on how you have your mappings configured (disabling _all or not)....

python fuzzy text search
python,elasticsearch,full-text-search,fuzzy-search,whoosh
{1} You can do this in Whoosh 2.7. It has fuzzy search by adding the plugin whoosh.qparser.FuzzyTermPlugin: whoosh.qparser.FuzzyTermPlugin lets you search for “fuzzy” terms, that is, terms that don’t have to match exactly. The fuzzy term will match any similar term within a certain number of “edits” (character insertions, deletions,...
Solr Fuzzy Search Weird Case
I believe you are running into a problem with query rewrites. Any multi-term query (fuzzy queries, prefix queries, etc.) gets expanded, in Lucene, into the exact terms that it matches. There is a maximum to the number of terms that can be generated this way though, so when rewriting the...
Lucene acting up on OrientDB when confronted with fuzzy queries
indexing,lucene,orient-db,fuzzy-search
The problem is letter case. StandardAnalyzer, SimpleAnalyzer, and EnglishAnalyzer all lowercase text before indexing the terms. KeywordAnalyzer doesn't. Since wildcard, fuzzy, and other expanded, multi-term queries aren't analyzed, the QueryParser, by default, lowercases these types of query. I don't know much about what OrientDB exposes of Lucene to allow you...
Elastic Search Distinguish Fuzzy Results
search,lucene,elasticsearch,fuzzy,fuzzy-search
Running two separate queries is the approach that makes the most sense to me. You could run two queries such that one gets only exact matches, and the other gets only fuzzy results, such as: exact matches only: purple car fuzzy matches only: purple car~ -car Which should make the...
elasticsearch fuzzy queries ignores boost factor?
elasticsearch,fuzzy-search,elasticsearch-boost
Boost isn't being ignored...you're just adding a fuzzy component to the score, which is changing the overall ordering. If you run the queries with ?explain=true, you'll get a debug dump of how the score is being constructed. With your first query, exact matches were required. Combined with the most_fields, scoring...
