# Search

A library for searching and sorting lists of data 
with fields `content: String` and `dateTime: Time.Posix`.


## Examples

The data is `colors` with elements of the form

```
type alias Datum = { content: String, dateTime: Time.Posix }
```

```
> colors 
  |> List.map .content
  ["alizarin yellow","brown umber","yellow ochre","pthalo blue"
  ,"french yellow","alizarin crimson, cadmium purple"]
```

Simple search
```
> search NotCaseSensitive "yellow" colors 
  |> List.map .content
  ["alizarin yellow","yellow ochre","french yellow"]
```  
  
Search on fragments
```
> search NotCaseSensitive "fr" colors 
  |> List.map .content
  ["french yellow"]
```

Conjunctive search
```
> search NotCaseSensitive "yell french" colors 
  |> List.map .content
  ["french yellow"] : List String
```

Negation
```
> search NotCaseSensitive "yell -french" colors 
  |> List.map .content
  ["alizarin yellow","yellow ochre"]
```

Date-time:
```
> search NotCaseSensitive "@before:7/1/2021" colors 
  |> List.map .content
  ["alizarin yellow","brown umber"]
```

Date-time and word fragment
```
> search NotCaseSensitive "@before:7/1/2021 yellow" colors 
  |> List.map .content
  ["alizarin yellow"]
```
