I have free text Narrative fields. I have to scan multiple keywords in this Free text field and find out strings (Partially or Exact Matched). For Example: Narrative Field: SUPPLY OF MANPOWER AS PER PROFORMA INVOICE DATED 14.01.2019 1. SIGNED COMMERCIAL INVOICE(S) IN 1 ORIGINAL AND 2 COPIES SHOWING DATE OF SUPPLY OF MANPOWER NOT LATER THAN 15.05.2019 AND DULY COUNTERSIGNED BY APPLICANTS AUTHORIZED SIGNATORY AND TO BE AUTHENTICATED BY IRAN NATIONAL BANK, ERAN TRADE FINANCE DEPARTMENT PRIOR PRESENTATION OF DOCS FOR NEGOTIATION. IN THE ABSENCE OF DATE OF SUPPLY OF MANPOWER, THE DATE SHOWN ON COMMERCIAL INVOICE WILL BE CONSIDERED AS THE SUPPLY DATE for DAWOOD HASSAN. USD 120/- OR EQUIVALENT IN THE L/C CURRENCY AND RELATED CHARGES SHOULD BE DEDUCTED FROM THE PAYMENT FOR EACH PRESENTATION by DAWOOD HASAN OF DISCREPANT DOCUMENTS UNDER THIS CREDIT, NOT WITHSTANDING ANY INSTRUCTION TO THE CONTRARY, THIS CHARGE SHALL BE FOR THE ACCOUNT OF BENEFICIARY 2. BENEFICIARYS A/C NO.: 202-577688-001-0010-000 BIC: PIBPBG2L APPLICANT ACCOUNT. ALL OTHER CHARGES INCLUDING REIMBURSEMENT AND SWIFT PAYMENTS RELATED CHARGES ARE FOR BENEFICIARY ACCOUNT in SYRIA WITHOUT DESPATCH FULL SET OF PRESENTED / NEGOTIATED DOCUMENTS IN ONE LOT BY COURIER TO: QATAR NATIONAL BANK, MAIN OFFICE, GRAND HAMAD STREET, TRADE FINANCE DEPARTMENT, IMPORTS SECTION, P.O. BOX 1000, DOHA, QATAR. ++UPON RECEIPT OF CREDIT COMPLYING DOCUMENTS OSMA BIN LADEN PAYMENT SHALL BE EFFECTED BY US AS PER PRESENTING BANKS INSTRUCTION. I have to scan above Narrative field and find out list of keywords given below PIBPBG2L OSAMA BIN LADEN DAWOOD HASSAN SYRIA IRAN The scanning should give Partially or Exact matched strings in above Narrative field. Here, the output will be: Matched strings for PIBPBG2L: PIBPBG2L (Exact Match) Matched strings for OSAMA BIN LADEN: OSMA BIN LADEN (Partial Match) Matched strings for DAWOOD HASSAN: DAWOOD HASSAN (Exact Match) & DAWOOD HASAN (Partial Match) Matched strings for SYRIA: SYRIA (Exact Match) Matched strings for IRAN: IRAN (Exact Match) & ERAN (Partial Match) Please note, I have to scan more ~1 Million such keywords in Real Time. So, please suggest for approach which could be faster. I am not using Like Wise match as this will be very slow for 1 Million records, also it will show exact matches only. To give you further details, I have to scan complete World Check Names in above Narrative field with Exact or Partial Matching.
