Placing Commas Between Names

By -

I am trying to find out if certain patterns appear within a data frame.

Suppose I have the following "dictionary of patterns" (notice "james" vs "jamesj"):

patterns <- c("john", "jack", "james", "jamesj", "jason")

The actual data frame ("date_frame") I have looks like this:

  id                                              names
1  1                                     johnjack jameS
2  2                             john/james, jasonjames
3  3                                    peter_jackjason
4  4                                   jamesjasonj jack
5  5 jamesjjason, johnjasonjohn , jason-jack sam _ peter

The final result I am trying to produce should look like this:

  id                                                         names
1  1                                             john, jack, james
2  2                                     john, james, jason, james
3  3                                            peter, jack, jason
4  4                                          jamesj, asonj,  jack
5  5 jamesj, jason, john, jason, john , jason, jack,  sam ,  peter

I tried looking at this post here (R: insert comma after each element from the output) and tried the answer provided there:

> data_frame$parsed_names = dput(data_frame$names)



  id                                                         names                                                  parsed_names
1  1                                             john, jack, james                                             john, jack, james
2  2                                     john, james, jason, james                                     john, james, jason, james
3  3                                            peter, jack, jason                                            peter, jack, jason
4  4                                          jamesj, asonj,  jack                                          jamesj, asonj,  jack
5  5 jamesj, jason, john, jason, john , jason, jack,  sam ,  peter jamesj, jason, john, jason, john , jason, jack,  sam ,  peter

But this is not corresponding to what I wanted.

I then tried this post over here (insert commas in text string after certain words in r) and tried the answer provided there:

library(gsubfn)

data_frame$parsed_names = gsubfn("\\w+", as.list(setNames(paste0(patterns, ","), patterns)), 
  format(data_frame$names))

 data_frame
  id                                                         names                                                         parsed_names
1  1                                             john, jack, james     john,, jack,, james,                                            
2  2                                     john, james, jason, james    john,, james,, jason,, james,                                    
3  3                                            peter, jack, jason      peter, jack,, jason,                                           
4  4                                          jamesj, asonj,  jack      jamesj,, asonj,  jack,                                         
5  5 jamesj, jason, john, jason, john , jason, jack,  sam ,  peter jamesj,, jason,, john,, jason,, john, , jason,, jack,,  sam ,  peter
  • Can someone please show me how to fix this?

Thank you!

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch")....

Hibernate Search - Elasticsearch with JSON manipulation

By -
Elasticsearch with JSON manipulation Elasticsearch ships with many features. It is possible that at some point, one feature you need will not be exposed by the Search DSL. To work around such limitations, Hibernate Search provides ways to: Transform the HTTP request sent to Elasticsearch for search queries. Read the raw JSON of the HTTP response received from Elasticsearch for search queries. Direct changes to the HTTP request may conflict with Hibernate Search features and be supported differently by different versions of Elasticsearch. Similarly, the content of the HTTP response may change depending on the version of Elasticsearch, depending on which Hibernate Search features are used, and even depending on how Hibernate Search features are implemented. Thus, features relying on direct access to HTTP requests or responses cannot be guaranteed to continue to work when upgrading Hibernate Search, even for micro upgrades (x.y.z to x.y.(z+1)). Use this at your own risk....
