Elasticsearch regexp on query -


i have following query works great:

query: {   multi_match: {    fields: ["first_name", "last_name", "email", "sku"],    query: query,    type: "cross_fields",    operator: "and" }

however, i'd have incoming query rid of non-alphanumeric characters, using regex:

[^a-za-z0-9\ @\.]

is there way have elasticsearch filter incoming query regex fields?

you can specify different analyzer search during query construction.

query: {   multi_match: {    fields: ["first_name", "last_name", "email", "sku"],    query: query,    type: "cross_fields",    operator: "and",    analyzer: "your-custom-analyzer" }

you have provide definition of "your-custom-analyzer" in mapping. analyzer definition can use pattern replace filter meet requirement.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
