# Elastic Search Query Generator
#### what is Elastic Search Query Generator ?
* While i was working with Elastic Search i found it very difficult to write complex queries as most of query are deep Nested
* Thats the reason i decided to make a helper class that can generate complex Elastic Search query in Seconds
* Library can be used to generate complex aggregation Query , Geo location Query (AND | OR | NOT ) any set of combination is possible
* in addition to all mentioned above you can also generate auto complete query in matter of seconds
* please see examples below on how to use this module.
* if you have any questions or suggestion please drop me an email at shahsoumil519@gmail.com
* Learn More : https://www.youtube.com/watch?v=C-JKcMM6IXE&t=2548s
## documentation :
* UML Diagram
* Constructor:
* Size: How Many Documents should the Query Return
* BucketName: is optional pass a name for Aggregation
* Source: Basically what fields you want to return takes a List Argument source= [“f1”, “f2”, …..]
* Min_score: used for filtering large documents average threshold is set to 0.5
* Field:
* This is column or field you would like to search
* Boost:
* If you want to Boost certain field pass a integer value
* Operation
* There are four main operation you can pass
* Should ( OR Operation)
* Must (AND operation)
* Filter (FILTER Result )
* Must_not (NOT Operation )
* Analyzer:
* you can specify various analyzer such as stop etc
## Installation
```bash
pip install elasticsearchquerygenerator
```
## Usage
```python
from elasticsearchquerygenerator.elasticsearchquerygenerator import ElasticSearchQuery
import json
def main():
helper = ElasticSearchQuery(size=100, BucketName="MyBuckets")
# match phrase
query=helper.match_phrase(field="myfeild", value="myvalue", operation='must')
# terms
query=helper.terms(field="myfeild", value="myvalue", operation='must')
# Feild Exists
query = helper.exists(field='comp feild', operation="must")
#Match
query=helper.match(field="MMMMM", value="myvalue", operation='must')
# Geo Queires
query = helper.add_geoqueries(radius="100", lat="22", lon="33")
# Aggreation
helper.add_aggreation(aggregate_name="FirstName", field="field1",type='terms',sort='desc', size=3)
helper.add_aggreation(aggregate_name="SecondName", field="field2",type='terms',sort='desc', size=3)
helper.add_aggreation(aggregate_name="ThirdName", field="field3",type='terms',sort='desc', size=3)
query = helper.complete_aggreation()
query = helper.query_string(default_field="DEFAULT",query="X OR Y",operation='must')
query = helper.add_geo_aggreation(field="AAAA", lat="22", lon="43",aggregate_name="my_distance")
print(json.dumps(query, indent=3))
if __name__ == "__main__":
main()
```

}
}
}
}
```
### Example 2
```python
from elasticsearchquerygenerator.elasticsearchquerygenerator import ElasticSearchQuery
import json
def autocomplete():
helper = ElasticSearchQuery(size=0, BucketName="MyBuckets")
query = helper.autocomplete_1(field="title",value="n", size=25,sort='desc')
print(json.dumps(query, indent=3))
if __name__ == "__main__":
main(autocomplete
```
```json
{
"_source": [],
"size": 0,
"min_score": 0.5,
"query": {
"bool": {
"must": [
{
"match_phrase_prefix": {
"title": {
"query": "n"
}
}
}
],
"filter": [],
"should": [],
"must_not": []
}
},
"aggs": {
"auto_complete": {
"terms": {
"field": "title",
"order": {
"_count": "desc"
},
"size": 25
}
}
}
}
```
##### i would be adding more examples and making it better and better
